I've been doing it that way for 20+ years on any *NIX system (including
different distributions of Linux) I've been involved with, and have
never once had any kind of complication or problem with it.  It's there,
it gets mounted, it gets used.

The only problem I've had was with trying to do a separate /etc
partition once.  Oops.  *That* one made for interesting times.  I think
I had to reformat and repartition after that one. :-)  Since it was a
fresh install, it just wasted a bit of time.

And when I'm doing something that requires it, I tell the installer to
format the /usr partition as well.  Not that hard to do. :-)

Yup.  But even if on the same physical disk, it makes way too much sense
to have a separate /home to not do it.
