I guess I'm misunderstanding something.  The scenario that I have in
mind is this:

  . we bump Emacs version to NN.1.90 as part of pretesting version NN.2
  . as part of the pretest, some function changes that requires
    addition or change in compat.el
  . compat.el still claims version NN.1, although it includes changes
    not present in Emacs NN.1

Did I succeed in explaining my worries?
