You rush to post a patch too quickly, sorry.  When Sean and myself
disagree, it is better to leave time to both of us to respond.

In this case, I'm against this method, so let's please find better
alternatives.

Pre-push hooks are an annoyance, because usually a push is supposed to
be a step that almost always succeeds.  Going back to commits and
redoing them is a terrible nuisance.  Moreover, in many cases I push
more than one commit, in which case rejection of one that is not the
last one is an even larger nuisance.

You seem to think about an LLM agent pushing commits?  How is that
possible if the agent doesn't have write access?
