New release group for instrumental versions?

[jesus2099]

There are already a few topics around this undecided subject.
Should instrumental, karaoke and remix release groups be merged with main release group?

For the 2 reasons that @Freso pointed out, I think the keep separate approach is the safest move, at the moment:

Karaoke versions of albums

I’d say separate. I was told previously than an acoustic and non-acoustic version of a Release (released at the same time) should be put in different RGs, and I don’t see how this is much different. With the “do I have this album?” implicitly question posed on the Release Group definition page I’d say that the two versions are not replacements for each other.

Should different remix singles be merged into one release group?

https://musicbrainz.org/doc/Style/Release_Group#Other_situations says (emphasis mine): There are a number of situations where there is currently no consensus about whether releases should be grouped together or not. This includes […] remixed albums. Be aware that attempting to group these releases can be quite controversial. If in doubt, these releases should probably be in separate release groups. So I’d probably not merge the release groups for now.
