This is an area where the decision of the SPF group to co-opt the TXT

We really need an architecture for extending the DNS that is not
predicated on rolling out new RRs for each new extension.
There is nothing bad about rolling out new DNS RR. The bad is that
certain current dns proxies do not make it easy and refuse to
recognize or let them through to dns resolver that can recognize them.
The bad is that to get around that people are taking over other RRs
and in that way creating conflict. But this argument has played out in
MARID to greater degree and I don't think we need full repeat of that.
BTW - obviously there is no way to support wildcards with _domainkey.
Something that implementors should be aware and so it should be
mentioned in the draft.
