My experience attempting to contribute to Manjaro (fixes to packages including some without with which packages simply hung when being built interactively, as they depended on stdin being EOF as it is in their CI environment) was met with not just a cold shoulder but active offense and hostility. They don't accept pull requests (in fact, their gitlab configuration doesn't even let one fork), nor is there a mailing list for patches. There simply is no contribution workflow, and this isn't even clearly documented (it's fine to be a "cathedral", but you should be up-front about it).
