In order to encourage reviews, and to prevent PRs from being created and merged without reviews within a short period of time (sometimes within one hour!), it has multiple times been suggested (on Discord, informally in discussions on PyCon) to add tooling that prevents an unreviewed reviewed PR to be merged unless a predetermined period of time has passed.

I think we should add a check that for unreviewed PRs will require a certain period of time to pass before the PR can be merged. This check will reset if new commits are added. If a review is performed, the check is dismissed. If a review if performed and new commits are added, the check is reset and a new review must be performed in order to dismiss the check again.

For discussion:

• Should this check be dismissed only when a core dev or triager has reviewed the PR, or should we allow external reviews?
• How long should the delay be? I suggest somewhere between 1 and 2 weeks. IMO, 2 days or even 3 days is too short.
