OK, but that's a really minor win; you're talking about *maybe* a few 
hundred extra memory-to-memory copies (for large queries/responses)--and 
they're all on the client side (a DNS server with ACE doesn't have to 
decode the ACE), so they don't affect scalability of the DNS.  That's a 
much smaller cost than introducing an incompatible format.
