Then how about a subdomain like "spf-conf"?  Even without the leading
hyphen or underscore that should have relatively low collision risk.
I'd prefer just to go for either a TXT record (with specified data,
obviously) or a new RR type.  In either case hostname rules are then
irrelevent.
Sorry, you've lost me here
The idea is:
4.3.2.1.spf-conf.domain.com   1D  IN  TXT spf=allow
                              1D  IN  MD  hostname
                              1D  IN  FOO bar
ie. Whatever RR we use, the zone it is held in doesn't contain the '_'
