How many old clients and servers do _NOT_ handle a 1400 byte packet?
When was the last time you saw one?
(The pix blocks it in some configuration modes I can add before you all
say _T_H_E__P_I_X_...)

that might be useful but will not solve the problem.
Could we just say "use EDNS0" and be done with it?
Legacy, i.e. EDNS-unaware, clients will continue to use the 512 byte
limit,
so the servers - unless they call for more load - should be
conservative
and the zone administrators should be as well.
Related to this, IPv6 already has an impact on server load. On our
system
we already see large amounts of AAAA and A6 type queries (each roughly
85%
of the type A count), so I'd really favor a conservative approach.
