How clean up Drafts?

Do I have a habit of starting to write a comment, then go "nevermind why am I bothering". Or I started saying something that I decoded is dumb and aborted (you're all welcome). Well at this point I have hundreds.

I can't find a way to delete them other then 1 by 1 and hitting confirmation each time. Am I missing something?

I thought about backup and delete storage or uninstall, but the DB backup that has settings in it also backs up drafts... I tried toggling save drafts off and on but that only applies to new drafts.

I guess I'd rather just not have drafts than have a forever growing pile but something like a setting to delete after X time would be a great feature. But in the short term, delete all seems like it would be relatively straightforward to implement?
