to be clear https://www.gnu.org/software/emacs/download.html does
point to https://emacsformacosx.com/ which would indicate it's
official in some manner. even the `brew install --cask emacs` (which
the download page instructs) points to these builds. i didn't realize
it's not considered an offical build.

ok, i just built it from source (haven't done that in years, not as
painful as it once was), but still the same issue.

yes.

i would think that any unbound key combinations should be passed to
the operating system, and with the *unofficial* railwaycat build, it
works.
