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)

btw, using font.current() is more natural at the lua end
