Not to defend Microsoft's existing design but I was under the impression
that we're using TXT because of bad design choices by the DNS team at
Microsoft.
Specifically, they can't query for a new RR type when behind an ISA
firewall.
The reason is because BIND needs to be upgraded to support a new RR
and that will take a lot more time and effort than just using something
deployed nameservers can use.
I don't think that the broken behaviour of one particular firewall is a
compelling reason not to use a new record type.
