Make sense.

One approach is to assume that new headers will be defined as SF, so

My question was also loaded towards the segment of people that use HTTP and
never put it in an open spec because they have no need for broad interop.
For example, if x-custom-thing was used between internal services then
there could be benefit in trying to align all header handling towards
structured headers without having to go and think hard about writing a spec
about it. Trying to define some generic framework for those folks is likely
going to fail so the I-D does right to avoid that trap. But a clear
statement along the lines of "the approaches in this document could be
applied to other HTTP fields" might stop a team bickering about the
practicalities of such a switch.
