Indeed, esc for Cancel and return/enter for Save still work - (which I actually knew, verified yesterday, and should probably have updated my post to mention before the annoying HN edit cutoff.) Are you running macOS Monterey? It doesn't seem to have a Don't Save option in the "Do you want to keep this new document" dialog box - it's Delete, and command-d does not work for me.
