I found that MusicBee supports it, but yeah, generally support for that tag seems to remain pretty exotic, and I've got no idea either whether any Android music players support it. Compilation albums pose similar issues, by the way. If I tag the release year of the compilation album, then the individual songs won't be filtered correctly if I want to do something like "play 60s music" or "play 70s music" etc. (and the same issue also applies to your "remastered album" scenario), and if I tag the original release years of the individual songs, then the positioning of the album will be a bit wonky (and I've found that some software uses the earliest date found for the whole album, whereas other software uses the perhaps somewhat more sensible latest date. I'm sure some software exists out there that simply uses the date of the first/last track [1], as well). Next problem is that support for timestamps more fine-grained than a year is equally spotty, so if an artist has released multiple albums in one year that don't happen to sort alphabetically, you also run into problems. To some extent you can override it by setting a custom sort order album name, but that can cause other issues elsewhere (i.e. when you do want to actually sort the albums alphabetically) and isn't supported by all players, either. Curiously enough, I've found that files bought from the iTunes store often come with a full timestamp in their tags, even though iTunes itself only supports years, i.e. you can only view and enter a year within the UI and the full timestamp doesn't even appear to be used internally behind the scenes, because multiple albums released within the same year are still only sorted alphabetically even if they have full timestamp tags with the proper dates set. [1] In fact iTunes does that for displaying the genre of an album – it just uses the genre of the first track, regardless of how representative that might be (or not).
