• Maybe two days instead of one?
• Mail to Dlang-internal?

To whom? I'm checking stable PR during betas, using a tinsy bash script.
https://github.com/MartinNowak/github_scripts/blob/62c7b0197f69d482e5dfbca55a950976fc681f09/list_branch_pulls.sh
Seems easier to do as part of the release script that to automate atm.

I check them at auto-tester: https://auto-tester.puremagic.com/pulls.ghtml?projectid=14

BTW the bot already recognizes stalled PRs targetting stable (see e.g. dlang/phobos#5981), so it would be just a matter of instead of labelling, commenting with sth. like:

Hey everyone, this PR is targeting stable and hasn't received any activity in the last three days. PRs to stable should be simple bug fixes or receive a higher priority. @: If you need help to finish this PR, join # on Slack.
