Not sure what you mean nor what would be the benefit.

A more direct way is to check (assq 'cl-generic package--builtin-versions)
which should not return nil (but does :-( ).
I haven't looked in detail at your patch, but it'd be good to do
something along these lines.
It's probably too late to use your approach for emacs-25, but I think we
need to install some fix for this problem in emacs-25, since otherwise
Emacs-25.1 will end up insisting on installing cl-generic from GNU ELPA
every occasion it gets.
How 'bout you install your patch into master and we install the patch
below into emacs-25?
