that might be useful but will not solve the problem.

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.
