I wish GitHub or Azure DevOps made this configurable (because I use them) - anyone know if any other hosted git systems have this as a configurable option?
Also, in the kernel generally you reference a different commit in a commit message with the form 'commit <12 char commit id> ("subject")'. So further restricting it makes sense.
In any event, I think teams should be free to adopt the workflow that works best for them without tools getting in the way. GitHub wrapping commit messages at 70 chars, even though I have more than plenty enough horizontal real estate, isn't helping anyone.
