I've been using it for all ports build since tmpfs appeared on FreeBSD.
Most of times, it is okay although I had to fix a couple of bumps.
There seems to be some corner cases as I see PRs come in.

Speaking of bugs, tmpfs may have problems if you do "mv a a" where
both source and target are the same; file may disappear due to some
bug with rename.2.  I tested with Linux and Solaris and "mv" prevented
problems with some of these archs.  But I forgot most of results and didn't
have time since then.
