The only thing I'm afraid of is that it'll get pushed onto the 
back-burner once it's in CVS, and we'll have a mad scramble to fix
it when it's time for 7.0.  That's not a show-stopper for it going
in, as there are also numerous benefits.  It's just something that
needs to be tracked and worked on.
