Does anyone have a strong objection to using unprefixed txt records?

If the migration to a new RR requires queries for ALL (NOTE: this should
be avoided if possible), then it will be easier to implement if there is a
prefix. TXT and new RRs can both be fetched with a single query without
worrying about overload conditions from SOA, NS, MX, etc.

As long as the magic label is short enough, then there's really no reason
not to do it.
