Of course eieio-defmethod and eieio--defmethod are still available, as
backward compatibility, and otherwise you can use the new

But in any case, such issues should be reported via M-x report-emacs-bug
rather than in

No, that won't byte compile the method: (byte-compile 'mymethod) will
only try to compile `mymethod' which is a generic function (which
dispatches to the various possible methods) and is already
byte-compiled anyway (I could imagine extending `byte-compile' so that
it understands the internal structure of generic functions and tries to
byte-compile all the methods when applied to a generic function, but
currently it doesn't do that).

You'd have to use

    (eval (byte-compile '(cl-defmethod mymethod ....)))

to byte-compile this particular method.
