The problem with this is that at the limit, this means "run the precommit on every save of a file," which is not really usually how people think of precommit hooks.
Given jj's rebasing tooling, rewiring precommit into "prepush" feels like the right way forward. There's a bit of a phase transition between commits on your machine and commits that are out in the wild, after all.
