We use several other repositories/review systems than Gerrit (Github, Differential, Gitlab etc). It would be nice to use the same commit hook for all of them, but right now it requires the Gerrit-specific Change-Id footer. It would be nice if that was optional. (Not sure how to pull that off; it could check the URL of the upstream repository, but I doubt a post-commit hook has access to that. Maybe a command line option for the installer?)
