If all your filesystems are full, you may not even be able to
modify a configuration file. With multiple filesystems, you at
least have a chance to move the offending files out of the way,
rather than having to delete it.

This situation should not arise often and may not be worth the
effort to split up your filesystems.

It slows down script kiddies. "Uhh.. how do I remount?"

And depending on your paranoia, you can use an environment that
does not allow the device to be remounted read-write. (I usually
do not.)
