Finally, often it is preferable to not spend lots of disk space and lots of time and/or bandwidth to generate or download rainbow tables, -- and also to not reveal your password hashes to a third party (such as one of the online rainbow tables based cracking services).
I don't think such a move (upload hash to 3rd-party site) is covered with any sensible pen-tester NDA (and related work).
(Though professional pentesters might have their own set of rainbow-tables) So, this is a good reason, still. cheers, Rainer
