Yes, briefly tested with HDMI, USB keyboard, also UEFI boot (just grub).

The only downside is the missing "boot" command. Not a big deal (as one
can always type "run bootmcd"), but quite inconvenient for the casual
user. If one (accidentally) aborts the timeout, just typing "boot" does
the right thing. This add ~450 bytes on my setup, so I wonder if we can
keep it in?

Cheers,
Andre.
