That's their choice.  I'd still claim that this is "lossy" (sender
with a broken policy will never know that his mail rots in some
junk folder and will be eventually purged.)  If the sender wants to
debug such issues they can use SOFTFAIL, and hopefully get reports.

The concept of a FAIL report confuses me, because it's at odds with
the SPF FAIL semantics.  As you said this would anyway only affect
receivers accepting FAIL.

BTW, SPF already permits a kind of tracking based on its "exists:"
mechanism not directly depending on the receiver policy. (Unless
"we never evaluate 'exists:'" is a part of this receiver policy.)

I'm no fan of these baroque SPF features, but they exist, and the
draft should mention that SPF FAIL reports are a rather odd idea.
