Hmmm...  Seems like "not writable by" might be more likely than "not owned by."  While I can't
think of a specific instance, I imagine that disallowing hard links in /tmp might confuse a
couple things.  

(But think of all the race conditions we might close!  Oh, wait, that's mostly symlinks.)

Yes it does confuse a few things. Not in /tmp, but surprisingly, in /var/spool/atjobs! I
solved it by augmenting the batch to allow an exception for system UIDs (uid < 1000, or
whatever you specified as an exception).
