I have noticed that too. And this looks to me like one more "Linuxism"
crept in into FreeBSD. In the past even those of us who came to Unix
trough Linux were following rule of thumb of keeping different sorts of
things on different partitions (or drives). Thus restricting the ability
of "one sort of thing" to screw up everything for "another sort of thing".
Such as:

/tmp (user writable, thus should be kept separate to avoid filling up /
and other system related area or just running fs our of file handlers)

/var (the place used for changing things, like logs, - can accidentally do
the same harm as in previous case)

/usr/local and /opt - to keep locally installed stuff separate from what
comes with the system...

Once (a while ago) I noticed Linuxes have started in addition to /tmp
using /var/tmp, and yet even worse /usr/tmp. What a brain dead decision!
It always is regretful when one sees "Linuxisms" creeping in into better
systems like FreeBSD ;-(

And yes, I know one can use quotas, and yes, I know zfs changes
perspectives ultimately...

Just my $0.02
