The question would be whether the downward reference is in accordance
with BCP 97. It is up to the IESG to consider whether a non-standards
track protocol which has not received full IETF review is in line with
BCP 97.
The citation you made from BCP 97 says that the standard needs to be clear and
interoperable. In this case, BCP 97 applies to the document under evaluation,
not to RFC4408, as the latter is Experimental.
The specification contained in RFC4408 has flaws that have long been
acknowledged and some new ones that have recently come to light, but despite
these it is operationally stable and its output is deterministic, resulting in
widespread deployment and numerous interoperating implementations. Given that,
I don't believe the proposed standard under consideration fails to meet the
requirements of BCP 97.
If and when the spfbis working group produces an update that fixes RFC4408,
and/or new versions of SPF come out that actually alter the output of SPF, an
update to this document that accommodates those changes could be made to keep
them aligned, as Barry has already pointed out.
