It's a good thing you can't force it, because `git commit -n` exists. (And besides, management of the `.git/hooks` directory is done locally. You can always just wipe that directory of any noxious hooks.)

I can accept (but still often skip, with `git push -n`) a time-consuming pre-push hook, but a time-consuming and flaky pre-commit hook is totally unacceptable to my workflows and I will always find a way to work around it. Like everyone else is saying, if you want to enforce some rule on the codebase then do it in CI and block merges on it.
