This is the type of argument that I love most - "if we permit this to you, 
everybody will want it, too!!!".

I read into this that you are afraid that the initial criteria are not
strict enough.  As far as I can see, the criteria are pretty explicit,
and verificable.

Please.  We have been through this part of the discussion half a year ago,
and we've asked those that know (the DNS WG) and they tell us "we can't
rely on EDNS0, and truncation is bad".  It would be very helpful if you
could do us the favour and read up on old arguments in the archives.

To repeat myself: it's not the AP WG's job to tell the DNS WG how DNS
works.  We're making policy, (partly) based on the expertise of other working 
groups.
