Would mounting /usr read-only really make your system more secure?

I mean, nothing in it should be user-writable anyway, and if someone
roots the box, remounting it isn't hard. It actually adds steps to
keeping all of those binaries (which live in /usr) your users might use
or abuse up-to-date. Having a cronjob which does 

	find /usr -type f -perm	-002

and so on isnt hard.

Dear heavens, the last thing I'd want on a multi-user system is the most
important filesystem being remounted several times a week.
