In any non-trivial module where the size really starts to matter, the
portions of unused code that we generate will probably make no difference
at all.

I'll also add that it can sometimes be very difficult to avoid generating
unused code due to target (CPython x.y, PyPy, …) specific utility code that
comes with its own dependencies, which then may or may not be used on a
given target. Removing the final 0.5% of code that is "unused in some
cases" is really not something I would want to invest days into, each time
we make a change in Cython.
