This would help with the complexity of downloading mods (mainly for new players), plus the speed of getting a mod downloaded (idk I think all this is pretty obv).
If this ever was a thing, there would be an approval process, and several of us would look at it before it would be flagged to be available in game.This could lead to various security vulnerabilities and might not be a wise decision.
That's actually a really good idea! Nice job.The host could possibly have a menu to choose what mods they don't want others to download
