Exactly like the current wildcard, it cannot be implemented only

I just made a test: The ** wildcard is correctly transferred by zone
transfers. At least with BIND 9.
Yes. But to actually use it, you would have to get this extension into
*every* DNS server out there, as each of them could transfer your zone and
try to interpret it according to the releveant RFCs. This is not a light
task.
Also, I believe that nobody who has to manage a significant number of hosts
in zone files will create the raw entries manually. Extending the macros
generating the A RRs looks quite simple to me (that's how I added SPF
records at work). So, I see no real need for such an extension (as opposed
to a new RR type for SPF).
