That's not viable, mostly because the performance cost of doing so is significantly time consuming, that it would block `git push` for minutes at a time, and all users performing pushes would have to wait in a queue for several minutes per push. At scale, I'd expect the push'es to start timing out. That's why the gating is done between git-master and rsync-master, not between the user and git-master. Just imagine needing to wait for a travis test run to complete on the end of every commit, stacked with there being 20 different jobs per push and having to use the slower non-container architecture. Nobody would be working on *that* project, or people would simply make much larger push-queues, increasing the amount of conflicts and progressive de-coherence. > > > I can see if it's something I need to fix with my code.

And so upon reading the original email hearing that people could even be notified of this fact, made me immediately question what I should be doing to see said notifications, or if there was even a page that I could check periodically to know what the state of the sync was. As the saying goes, information and awareness of the problem is a critical first step to solving the problem.
