a lot of it comes from a heavy legacy; i think MS Paint couldn't save PNG transparency back in the day.
in the end it doesn't really matter what color the background is, as long as it isn't a color already used by a color index of the sprites themselves. nonetheless, an ideal sheet is one with a transparent sheet background but with nontransparent sprite background (or vice-versa) because that's the only way you can preserve animation alignment (for example this https://www.spriters-resource.com/playst...et/151285/ ).
