   The problem is that lots of packages use `s-prepend', rather than
   `clos-prepend'. There are too many packages that are blocked on being ELPA
   because of s.el and f.el (as dash.el is on ELPA).

Then those packages should be modified to not use s.el/dash.el/f.el
before they are included in ELPA.  Just like that would be a
requirement for them to be included in Emacs.  

s.el could be modified in such a way that it would have compiler
warnings for the functins that Emacs Lisp already has, and where there
are different semantics encourage to use the Emacs Lisp way of
writting.  The functions that do not have a equivalent could added in
subr-x.  Users would then, slowly, migrate their code, and make it
easier to include things in ELPA in the future.

This is just a matter of following the good practises that already
exist in Emacs.  It would be a bad idea to start making a mess, and
then encouraging this mess to become larger.
