This is cool, thank you.  In my case all my frames are created with
'emacsclient -nc', however, so this command is not much use on its own.
Could there be some sort of hook so that I could arrange for Emacs to
execute (make-frame) or something after the restart?

Well, in this case I just want a single frame to be opened, rather than
saving and restoring all that state.  I guess what I want is reexec with
additional command line arguments, "--eval" "(make-frame)".

I think that's out of scope for `restart-emacs'.  I mean, it would be
possible to have a
`restart-emacs-but-with-extra-command-line-arguments', but then you're
not restarting Emacs the way you started it.

But if you start Emacs originally with "--eval" "(make-frame)", then
`restart-emacs' will be restarted the same way.

Right.

Interesting idea, thank you.

A related out-of-scope request would be to `start/call-process` a new
instance of the running Emacs, as needed for `async.el` or
`elisp-flymake-byte-compile`, which currently relies on
(expand-file-name invocation-name invocation-directory).
