BTW, I think so far no one has stepped forward to implement the custom
argument handlers. I've looked at Cython output and, as you say, most of
it is there already.

Is it possible to write a minimal version of the code generator that just
produces the argument handling code?

Approximately, how many lines of code would we be talking about?
