To some extent, sure, but I think that extent is greater with Homebrew. It's my understanding that package maintainers for Debian, RHEL, etc are typically experts in the packages that they maintain. They overlay their own patches to ensure compatibility and submit patches upstream. With Homebrew there's only a small number of committers who maintain the homebrew-core repository, accepting PRs from thousands of people in the community. It's just a different situation.
