Just to clarify… you want to be able to display (music) albums on the People pages in addition to the existing media such as movies and shows?
I suppose the tricky part about that is to actually linking that information. There’s a lot of same-named actors/artists who are not the same person, so Plex will need to depend on some unique identifier for both worlds – and while a number of artists have their own IMDb ID, that won’t be the case for everybody; nor will the music metadata providers necessarily reference IMDb for music releases.
Not saying this cannot be done but sharing my 2ct that it’ll probably a more complex endeavor (especially considering how many users rely on embedded metadata for their music).
