Please put this statement right at the top of your cover letter.
Probably in shorter form. "Specification still undergoing review,"

This changes this puts a big external dependency on the patch set
(I'd have preferred this remained an RFC but I know others asked for
that to change!)

Given limited review capacity I want people to make a decision on whether
they wish to review knowing that the specification is still potentially
in flux.

A such I for one am going to hold off on reviewing new versions until
you post a patch that at the top of the cover letter says.
"Specification is now reviewed and has moved to the stage where we can
rely on it as being stable + ideally a pointer to an errata process so
we have a grasp on how specification fixes are handled.

Thanks and good luck getting to that point!
