To expound a bit more, an I-D that gets approved to be an RFC while
including a normative reference on another I-D will get stuck in the
"MISSREF" state until the depended-on RFC is also ready for publication;
this generally also includes the creation of a "cluster" or related
proto-RFCs.

It is perfectly acceptable for final, published RFCs to have *informative*
references to I-Ds, even I-Ds which are not necessarily expected to be
published as RFCs.

This results in them both getting published at the same time, but that is
probably fine.
