AFAIK it's not *incompatible*, it's just that the dispatch functions
generated by cl-defmethod stay as byte-compiled, because they're
dynamically generated rather than being written into a .elc file.

There's a lot of room for improvement in this area, but I think it will
inevitably require specific treatment.  While the speed of execution of
those dispatch functions is important, the speed with which we can
(re)create them is also important, so a naive approach of passing it to
the native compiler to save into a temp file which we then load is
likely to be too costly in some cases.
