We don't automatically pull changes, our community improves and try to test it as well. We know that the recent PRs of Ernest are far from perfect and in fact the recent PRs are often not feature complete. The only reason Mbin is trying to sync from kbin we try to keep the code base in sync for now (if we as a community agrees on the changes). We DO make changes to the PR like you can see here: https://github.com/MbinOrg/mbin/pull/212 And we also follow-up with additional changes, like you can see here: https://github.com/MbinOrg/mbin/pull/225
