What I imagine is that you could have some old packages that you probably want to delete because they're so old, even though their deps have not changed. Meanwhile you have some packages that are relatively recent and you'd like to delete them if they have changed deps. Given the current logic, I guess you'd have to do separate passes, one to delete packages based on age and another to delete packages based on changed deps. Maybe it's fine to require separate passes for this kind of thing. I supposed the alternative would be to add an --or flag that would allow you to say that you want to delete packages if they are at least a certain age or they have changed deps. -- Thanks, Zac
