Well, yes in principle (but no in concrete).
My use-cases are often in a release title, e.g. in the question if a subtitle is included or not. Sometime I’m adding a kind of subtitle and sometimes I’m cut off parts, which are not relevant for me. Also for track titles I have sometimes changes in my tags (for different reasons).
This are usually cases where both variations (the MB-value and my personal value) are acceptable and correct values but not so clear, to change the value in MusicBrainz. If I find definitely wrong data in MB I’m typically correcting the data in MB.
In your example, a deluxe edition, I would rather and typically enter it as new release in MusicBrainz, if it doesn’t exist - even if nearly all other data is equal (same tracks but maybe different packaging, typically also the title would be the same; just a proper disambiguation should be used). Adding such similar releases is just an easy task and since only one field is different, it’s also correct to add it.
However, it would be possible to handle it with my planned plugin.
P.S.: My planned plugin works with shadow-tags. Also because of problems on .m4a I’m not sure, if I will continue with it.
