However, the following additions to SPF could kill my implementation:

- RR types (not supported by Windows DNS API AFAIK)

ESMTP command after or before MAIL FROM, I could definitely make it work).
Isn't it a bit ironic that these items are recent (Microsoft?) proposals?
No, actually. Microsoft is in the business of selling new software. They
don't make a dime off people extending their old stuff. I'm sure they'd
be very pleased if everyone had to go out and upgrade Exchange to make the
New SPF work.
