20741,  so direct SPF RR hits is about one third of those using TXT RR,
small, but, insignificant? I wouldn't really say so, but some might.  I
suspect the SPF wanting to be deprecated is because of the lack of
take-up, due to lazy admins, there are some resolvers in use from
ancient debian boxes that are so old, they dont understand the SPF RR,
yes I know, they have bigger problems than that, but, again, comes down
to laziness, DNS is not rocket science, I'm sure given ARM and access to
google, a 13yo kid could get at least the "basics" right.
