Possible mitigation for forgetting phabricator subcriptions for {llvm, cfe}-commits?

Does phabricator have a way of changing the default commit message template through the per-repo .arcconfig?

Making the default template include the appropriate mailing list automatically might go a long way to mitigating our problems. It doesn’t help when uploading through the web UI though.

It would be better to use Herald rules for this. Herald can
automatically add reviewers/subscribers based on specific conditions.
