The 2 drawbacks with SU are
1 - You can't immediately reuse the space occupied by a file you just
deleted; this may bite you if you do an installworld and don't have
20MB free on /. when it comes to installing /sbin, you need 18MB
for the new binaries, but you can't reuse the 18MB for the
just-deleted binaries.
2 - If you create a file, SU doesn't commit it immediately; it waits a
bit. If you edit rc.conf and crash (or reboot by power-cycling),
you may find you don't have an rc.conf.
Both have happened to me enough times that I don't enable SU on /
anymore :)
