I remember that message, but i don't see Stefan proposing to use
Lisp_Object for anything there. I didn't answer to it directly because
Pip answered and what he said was right.

The situation that Stefan overlooked in his analysis is one like
x-file-dialog in ns-win.el. This is a native compiled function, so a
SUBRP, but _not_ a primitive function (C function). Remember me
wondering how we land in nativecomp code for x-file-dialog in the
beginning? Same thing.
