Certainly seems intentional: notice the lack of qemu_console_is_graphic checks
in sdl2.c compared to sdl.c. My guess is Dave just ripped it all out since it
was tangential to the original goal of facilitating some virtio graphics magic.

But the side effect is that sdl2.c isn't a suitable replacement for sdl.c
quite yet :/

There was some attempt to wire this up, sdl2.c:487. If I do
s/SDL_SCANCODE_KP/SDL_SCANCODE/g it will make the keyboard shortcuts actually
trigger the zoom code, but it still doesn't seem to work.

(In fact, sdl.c doesn't work for me either: it expects:

        case 0x1b: /* '+' */
        case 0x35: /* '-' */

But for me, '-' is 0xC and '+' is 0xD...
