To be exact, all macros can be cached (except "t", timestamp, of

The point is that the text included in the RFC gives you a clear idea
of what MS thinks about what is reasonably cached and that was the
original subject. Knowing the IP and domain will let you correctly
cache the vast majority of SPF records. Everything else is way past
the point of diminishing returns.
Agreed. But the _real_ point, I think, is that MS do not only not _cache_
records with the "s,l,o,h" macros, but do not _use_ them at all. Which is
bad.
Why did MS say they are doing this way again?
