I get nothing because you rmwe is really minimal in the sense that
font_switch is not defined.
Anyway, what you need to do it this:
\number\fontid\font
which will work in mkiv and lmtx or
\the\fontid\font
which also works in lmtx.
I changed a couple of these 'internal quantities' to behave like number
tokens which has some advantages (for instance, such a token doesn't
need to have a space or \relax as sentinel in situations where a
lookahead can spoil your game). There is a whole bunch of these
quantities and some were numbers and some serialized numbers and i just
made that consistent across the repertoire. It's anyway good practice to
put something \number in front when you wonder of what you get is a
number. Just consider it progress.
(there's also \setfontid so maybe you don't need the lua code at all)
