The IMAP specification treats them as a fairly scarce resource.
I haven't done a survey, but IMAP servers aren't required to let
you create new ones not on the "approved" tag list.  I think you
can have as many as you want, but I'm not sure what the limits
w.r.t. tags are (they're really supposed to be boolean things).
