[DG] OK, makes sense

Regarding the discussion between Michael and Eli on the most efficient way to proceed, if you have a patch that can be applied to 26.2 I could certainly give it a try. Or I can try next version of emacs once released.

If you want to try to prompt the relevant binary distributors to patch, I believe I am pretty typical for current macos emacs users in that emacs is installed via "brew cask install emacs" which I understand obtains its binary from https://emacsformacosx.com/.

Thanks.
