Quick thought: Should this be a draft until it's ready for review/merge? Open PRs ping all repo watchers every time there is a new commit (not sure if that's what you wanted). I'm pretty sure drafts don't send notifications.

sorry about that. I was not aware to be honest.

Neither was I until someone told me! :D

Edit: I think I was wrong. I realized that I get notifications about other PRs that are just drafts. After some digging it looks like repo watchers are auto-subscribed to draft PRs too, so are notified about all pushes. Sorry for the noise!
