But the point of the _ui and _si functions, as I understand them, is to
make it safe and easy to pass values between code using GMP and code
which is unaware of GMP types.

One can have alternative functions accepting mp_limb_t and
mp_limb_signed_t, if one finds that useful. But for the above reason,
advertising such functions as a substitute for the _ui and _si functions
seems to totally miss the point.
