An example of another area we do not have. Printing “Made in EU” made it easier for people like EMI to print in Swindon, Uden or Italy and not worry about changing the labelling.
I was hoping to keep this focused on the one question - why Holland? - and not go back over too many old threads… 
There are older threads on “no EU”, “No Historic Locations”, etc which is what makes this Holland so odd
There is an ISO list of countries… I assume Holland is not on it! not sure about EU. why not use that?
Yes, this one too.
This kind of release often happens.
I link Netherlands as Holland and Europe as EU or as E.U., with our without the the prefix, depending of the print.
Hmm… EU stands for European Union and there are number of countries, including Russia and Switzerland and Norway etc…, that do not belong to the EU. Europe is a continent.
Please send the EU debates to one of the many dead and ignored threads: Search results for 'europe' - MetaBrainz Community Discourse (and I totally agree, but MB is not interested in fixing that one)
This is a different issue. As @dpr points out - this is not on the ISO list of countries.
I have not checked instances efter reading this thread, but anticipated it: while adding as per printed ‘Holland’ the only area offered by the drop-down, noticing the disambiguation ‘historical’ being shown only afterwards.
There are a number of MB-systemic traps. 2 more:
• Release artists should be separated by comma. But when adding another artist, the system auto-separates the last one with ‘&’ that needs manual correction.
• Typographically-correct punctuation is preferred. Typically, a classical sonata movement with slow intro should be written “Adagio – Allegro” (with ‘en dash’), but the track text parser uses that same sign as a separator between fields (making ‘Allegro’ track artist, and ‘Beethoven’ an invalid duration), which needs manual correction.
This is only true for classical! See classical style guideline (CSG)'s section about release artists. 
Thus the automatic “,” and “&” as basic defaults for all other kinds of music tracklists, because it’s the most often printed join phrase.
But it can be replaced by ft, feat, with, avec, depending on what is printed.
Still, system itself deviates from the very CSG it tells editors to follow.
These things could be offed with by a SG/CSG toggle.

Hopefully someone will fix this one day… but until then all we can do it police it and move things to the correct country. Thank you @spUdux for spotting this and correcting to many of those obviously wrong entries. I know how many times myself I selected “Holland” for a Printed in \ Manufactured in credit.
Okay - that is odd. There are no no open edits (thanks @Kellnerd) but still the Artist and Labels have not moved. Don’t know why they don’t register as edits. Guess Areas are “special”
https://musicbrainz.org/area/0c9c6488-6c6a-47ec-8f9e-dc5b69941d25/artists
https://musicbrainz.org/area/0c9c6488-6c6a-47ec-8f9e-dc5b69941d25/labels
Odd indeed, actually there are quite a few open edits e.g. https://musicbrainz.org/edit/86096615
And thank you @IvanDobsky for your contributions here and overall dedication 
edit: those open edits show up only on the artists and labels in question 
We are learning something new - “open edits” on a entity does not mean ALL open edits on that entity.
It is also a pity that an area can’t be subscribed to. I was going to subscribe to this to keep corrections in the future. Just have to remember to check in now and then.
And I waded in and helped do the fixes here as I realised many of the “manufactured in” links were made by me in the first place. 
I like to add those kinds of details from my CDs. And as I noted above it seems many of my locations don’t exist - EU, Holland and W.Germany. 
You can add it to an area collection “Dodgy areas” and subscribe to that, IIRC? (then others could subscribe too).
Thanks for the workaround hint
If anybody else still cares, here’s the collection you can subscribe: Historical Holland
Holland and W. Germany existed at one point in time! Holland stopped being a country before CDs started being made.
The EU is still in existence…Maybe the conclusion of this discussion is that this field is not a country name, but a economic region. ‘Made in the EU’ is obviously a way of providing flexibility in picking a manufacturing location while indicating enough information for import/export tax purposes.
