Do you know how slow all of that is? Do you want to run all of that per every commit? The result would be people making a monocommit rather than incremental commits that is easy to review one by one.

I do like pre-commit for enforcing linted and typed code but the speed (or lack thereof) does hurt.

Yes, so fast that it makes no difference at all to me. How slow do you think black is?
