It would be really great if operating systems (and applications) didn't have to be constantly cleaned up in the first place. Way too much software uses the user's filesystem as their personal dumping ground for crap. Crap that they leave around when not running and crap that they leave behind when they're uninstalled. My ~/Library directory is currently 47G(!!) and it's mostly a bunch of shit that I have no idea whether I need or not. As the user, I should be the one who decides what to put on my filesystem, not some application developer. We've completely lost control of our own filesystems.
