	I think we should simplify the number of ways we do something,
be it edns0 or tcp.  We are seeing the difference in everyone wanting
their own way/transport/whatnot and therefore keep growing the methods
to get the same data.

	But yes, as we increase the default answer size with additional
glue, signatures, validation, we should be following and sizing as
appropriate.
