Sounds nice. Maybe if you combine it with the suggestions from https://lists.gnupg.org/pipermail/gnupg-users/2018-May/060362.html (and perhaps improve my proposal, as a first guess usually cannot be the best), you could kill two birds with one stone. Hence you also could have a shorter path to get rid of old ciphers, MDCs and other backward compatibility stuff, thus increasing security and speeding up development.
