A feature worth implementing would be the application of specificity to the automation of deleting PMs. For example, take from the PM rich, and let the PM poor keep what they have. By that, I mean letting someone with 30 (or so) PMs keep them regardless of age, and remove the old PMs from those with far more, applying the focus where it is truly needed. It would just be sad for someone with only 30 PMs to log in and find what little they had was entirely gone. I'm not saying those with 3,000 PMs "wouldn't" care, but I highly suspect they'd care far less about loosing excess than certain others would care about losing everything.
