Against my better judgement, I did it on a server that was providing 
primary domain name service for a domain I care about.  It seemed to go 
without a hitch.  Then a few hours later I noticed that DNS lookups for 
that domain were failing, but other domains served by that same instance 
of bind were just fine.  I'm not sure why, but a bogus CNAME entry 
(which was indeed an error) in the db.thatdomain file was causing bind 
to quietly refuse to load that zone file.  Otherwise, I haven't noticed 
any issues, but I haven't tried it on any other servers yet as that made 
me a bit skittish.
