Thanks.

Your intuition was right (i.e. the code you wrote was the right choice).
I pushed it after removing those warnings as well as commenting out the
compile-time warnings from cl-defmethod (which is useful to move to the
new style but for now would be too annoying for third party packages
which have to maintain compatibility with Emacs<28).
