If the hosts behind it stop using 2002::/16  addresses as a product of a software update which seems rather more likely 
(also there some evidence for that), it will. that said yes one assumption is that you have to continue to support it.

It is really hard to justify the expansion and deployment of new relays =

Which may or may not be a short term dip.

correlation is not causation but...

 We are yet to see much in the
way of IPv6 only content.  When that appears, which it will, the tunneled
traffic will go up unless ISPs have deployed native IPv6 to all customers.
Are you willing to bet on which will happen first?

I'm willing to bet that subpar experience due to auto-tunneling is considered a liability for content providers.

This whole area is in a state of flux.

What would have been much better would have been to encourage CPE
vendors to release images which address some of the known issues.
Just adding a check box saying "enable 6to4" and for ISP to send
out email to say "check your router vendor web site for fixed
images".  The better fix would be to get them to also add support
for draft-andrews-v6ops-6to4-router-option-02.txt which greys out
the checkbox when 0.0.0.0 is sent as a response to the option.

Remember operators are in the position to alleviate lots of the
6to4 issues themselves.

Blocking AAAA over IPv4 transport is just silly. It's just as likely =
=3D
that your
AAAA record is destined for an end-host that has native IPv6 =3D
connectivity
with an intermediate resolver that desn't have IPv6 as it is that =3D
you're
sending that to a 6to4 host. Further, there's no reason to believe =
the
6to4 host won't attempt to resolve via IPv6, so, it doesn't really =3D=

anyway.

I agree, but, it's not hard to run 6to4 relays and running them does =
=3D
much
more to alleviate the problems with 6to4 than anything you proposed
above. Indeed, what you proposed above will likely create more =3D

issues rather than reduce them.
