User specified compatibility
Idea from hphpanon in the discord
Another possible solution would be to allow Mod Loader users to maintain their own compatibility lists. Like, in this BR Pills/MCF situation, it'd be nice if I could write my own xcl.meta that would serve as a sort of default metadata. Something to let me say "BR Pills and MCF are compatible", but if either BR Pills' or MCF's metadata contradicts my file, their metadata would get precedence.
