This already works out of the box with --alternate-editor='', no need
for any argument forwarding, and no need for support for this argument
in Emacs itself.

It doesn't work with --alternate-editor=emacs, but I think that is OK.
I think the alternate-editor='' configuration is far more common, and
that works just fine.

And we have not before done any special casing for forwarding arguments
from emacsclient to alternate-editor=emacs, so I don't think there's any
reason to start now.  (I personally think that alternate-editor=emacs is
somewhat ill-advised, since it doesn't ensure that the server gets
started)

That being said, supporting --apply in Emacs itself is fine with me,
although it's not strictly necessary since in Emacs itself,
--apply func --
is basically equivalent to
--eval (apply func command-line-args-left)

(This doesn't work in emacsclient, and would be very difficult to
support, so --apply is necessary for emacsclient)

I'm fine either way.
