This isn't so much a matter of high security as it is stupidity
prevention. How many times have you su'ed, and then when you were done
with whatever task you were working on, went and read your mail and
news, and editted a few files.

The next day you try to edit those files or read mail, only to
discover that root owns those files, because that's who you were when
you were using them last. 

More worrisome is when you wander about trying things, leaving a trail
of root owned files in your wake, because nothing is preventing you.
