Possibly. I think that the engineering decision as to whether version
3 should use the same typecode or a new one should be left up to the
designers of version 3 -- there is little point in debating it now,
given we have no idea what version 3 might be.
But given this is going to be the first SPF-syntax record to be
defined, I'm in favour of just calling it SPF. If version 3 wants to
use it, they can. If they want a new typecode, they can define SPF3.
Calling it SPF2 doesn't prevent version 3 from using it, but it will
make the naming look a bit silly if the designers of version 3 make
that decision.
