yet, so I apologise in advance if I'm going over things that have
already been covered.)

Hm, yes, that could also make sense.
I was pondering whether it would make sense to allow having events from
different devices in one key sequence. For instance, having the footpad
be a prefix key:
(keymap-set global-mode-map "{footpad-name}-b f" #'do-something)
(keymap-set global-mode-map "{footpad-name}-b g" #'do-something-else)
I think that could potentially be useful and powerful, so extending the
key syntax with the device name might be the way to go.

Yup.

Yes, that does seem like a handy way to deal with this use case.

Yup.
