I just tested with master and, indeed, the hook is executed. However, to
be effective for all invocations of make-frame the user must add the
function early enough (which means `early-init.el`.) When emacs.el is
processed it is too late as the initial frame (the frame created by
simply invoking emacs without parameters) already exists.

Maybe we could expand the docstrings of the hooks and/or make-frame to
note that you need early-init.el if you want your hooks executed when
the initial frame is created.

Otherwise, this bug can remain closed.
