Do I have to support PVR + Music for repo submission?

I just don’t have the use or time for either, so seems daft putting in some generic rubbish.

Can I just delete all the relevant files to do with PVR, music etc., or would skin be rejected?

I thought I read a while ago Kodi was heading in a ‘modular’ direction, being able to split off engines. Albeit I think you mainly meant video engine splitting from GUI?
Allowing user to install whatever they wanted.

Would be good if there were skins that just dealt with Movies/Tv/Video, and users were notified of this in a category.
Especially as Music is such a minefield of different infos/tags/etc. It’s a whole specialist subject on it’s own. And I wouldn’t know where to begin with Radio!!
