Why multiple filesystems?

What is even less clear to me than why procfs isn't good enough for what sysfs does is why procfs isn't good enough for what debugfs does.

The /proc name space did get messed up when people decided to put stuff other than process information (pid entries) in it. It would make more sense to call it something else and have a 'proc' directory in it for the pid entries. But other than that, I can't see why someone would object to having a debug interface in /proc but not object to it being in /debug.

As a kernel developer, I don't see anything that would make me want to learn a whole extra interface rather than put my debug interface in /proc.
