I’d welcome discussion on this. E.g in extents.c:5448, an extent’s keymap must have #'keymapp give non-nil, so autoloaded keymaps don’t work; keymap.c:773 maps using keymap_submaps_mapper_0 to force loading of those maps to be autoloaded, and that doesn’t work; as far as I can see, mapping across autoloaded submaps hasn’t worked since 1997.
