I'm not sure we enforce signed-off-by in all projects, but we do in the
most important
projects. There is a nice little app adding CI check with zero effort. Here
is
a bad commit:
https://github.com/nirs/userstorage/pull/29
When the check fails the app provides useful help for users:
https://github.com/nirs/userstorage/pull/29/checks?check_run_id=9125092601
Looks like very little effort to improve all projects!
If you wandered what signed-off-by means, this is explained here:
