It is not useless- I am specificallyt talking about setting
it up 
initially so that technically capable people can use and
test the 
infrastructure without breaking anything for those people on
v4 that have 
misconfigured v6 tunnels and the like (something that is not
at all 
uncommon with Vista). If you just turn on AAAA records for
www.google.com 
right now, lots of people will end up being unable to
connect to 
www.google.com because of a broken tunnel- and right now
ISP's are not 
primed to help their customers fix the problem.

Agreed.

 From experience, (see: http://ww
w.nanog.org/mtg-0405/pdf/lewis.pdf) I 
have done this.  I don't think I spent much time on that in
the 
slides, but we did start with things like "ww6."
and "ftp6."  It let 
us put up servers in a production environment and see them 
functionally work.

But the value in doing this is limited.

First, it can't/doesn't draw enough load to give an accurate
feeling 
of whether "IPv6 works" because the only ones that
know about it are 
those you tell.  (Not that IPv6 volume is all that great.)

Second, it isn't stable (long run) because you have to
eventually use 
the same names for all network (IP) versions.  You'll have
to ween 
the early adopters off the special names at some point.

I would say that this is something folks should just do to
make sure 
the servers come up and answer.  But it not much of a
"coming of age" 
step.
