I'll probably take a crack at this myself later, but I figured I'd open a formal issue in the meantime. It would be really useful to be able to package mods as 7z or zip files, and would probably reduce confusion. I know there's tooling for MPQs, but it's just an extra unecessary step. From what I've read, the main reason it's using MPQs is because using a Blizzard archive format is funny, which is...kind of a terrible reason.
