Processed bounces housekeeping

Your software
My Mautic version is:5.1.0
My PHP version is:8.1.27
My Database type and version is:MariaDB version 10.11.4

Your problem
My problem is:Know when to delete bounce messages

Although I admit I could’ve overlooked this information, I’ve seen no reference on how to handle bounce message housekeeping.
From what I understand, it should be safe to prune messages that already have been processed (marked as read?) sitting on the IMAP server.
Can someone please confirm this?
Also, wouldn’t it make sense to have an option in Mautic, like “Prune messages after processing"“ in which it would issue the appropriate STORE/EXPUNGE commands to automate message recycling?

Thank you!
