Always looking forward to your kind words.

I wouldn't be surprised if there are problems in this area, indeed, but
"not possible" doesn't match my experience:
ELISP> (cl-defgeneric sm-foo (a))
:autoload-end
ELISP> (cl-defmethod sm-foo ((a (eql 1))) 2)
sm-foo
ELISP> (sm-foo 1)
2 (#o2, #x2, ?\C-b)
ELISP> (cl-defmethod sm-foo ((a (eql 1))) 3)
sm-foo
ELISP> (sm-foo 1)
3 (#o3, #x3, ?\C-c)
ELISP>

Sounds like a bug or a misfeature, indeed.

I don't know what you're referring to. Could you point to those debbugs?

I don't think cl-generic.el is more magical than the rest of Emacs, so
`M-x report-emacs-bug` should work to submit patches. At least I can't
see how `M-x report-emacs-bug` could fail to submit a patch just because
it's about cl-generic.el.
