Certainly there would have to be a bunch of checks and balances, not blind acceptance, capturing source code URLs, checksums and the like, potentially reproducible builds, but could be a way to ‘crowd source’ packages. Or is this a solution in search of a problem?
And it's not about "saving the time to recompile", it's about using the source code so that you can keep using the AUR as long as the compilation process does not break.

Gentoo is a true dev OS and it's not for the meek for sure, but I've grown to love it. I really should contribute more to Void and start making package for it. I think it's one of the best up and coming Linux distros.
