Including it adds to DMARC's operational complexity and when SPF is
relied on, it makes DMARC's scope of use smaller, given the path
limitations.
If SPF support were eliminated from DMARC, what actual change in DMARC
utility would this have?
Yes, SPF has drawbacks. But it is still trivial to implement and makes
DMARC easier to implement as well.
