ooh, as @rdswift knows, I have strong opinions on this (missing your excellent full packaging scans by the way…)
Firstly, welcome @U2joshua!! I can’t express how much I appreciate the time it takes to scan and upload images, and how important it is to musicbrainz
Anyway… in a tagging sense using a nice high res digital cover is indeed the way to go. If we could only store one release/cover per album I would absolutely say to go for it.
However, we have support for multiple releases, and a useful ‘set cover art for release group’. It’s a piece of cake to add the digital release as well, that has the artwork you want, if you feel very strongly about that aspect. Frankly, apart from ‘can’t be bothered’, I can think of no excuse not to do so.
I’m not sure if Picard has an option to tag with the release group cover yet (?) but imo it’s a step backwards to put the ‘best’ (according to the editor) art onto all the releases before that happens… why even have covers for individual releases in that case.
