Then fix what's broken. If these projects need manditory reviews fine but
don't take a one-size-fits-all approach.

Requiring pre-commit hooks which run these could be helpful. They could
stop this at the local machine. Perhaps also a reminder to check ci. Not
sure this completely solves the issue but it would be workable for small
projects like kdiff3 and would reduce overhead for minor typo correction.
