Regarding indexing a creator's videos that aren't OtoMADs/YTPMVs as well as regular MADs/YTPs

I wanted a second opinion on something that came up while indexing yamas' work. Since yamas is such a prominent creator and some metadata regarding their work remains a bit spotty, I've gone on some spurts to list anything I can find on these videos. But I've noticed that some of these videos aren't really OtoMADs, such as the WarioWare edit and a MIDI cover I've linked above. While I'd like to preserve lost metadata as much as possible for creators like yamas, these kind of videos don't really belong for this kind of database.

So for future reference:

If the creator is notable enough, should we also try to index their non-OtoMAD/YTPMV works or should these type of videos be completely ignored for this database?
