I'm not super familiar with the perl/C API, but where would you do
that? The Network.c file is autogenerated. Maybe you would need to
add a PPCODE block to Network.xs? Maybe just copy the autogenerated
definition from Network.c to Network.xs and make this change?

I don't have a strong opinion either way, but if we remove it entirely
it is possible that someone will add it back in the future and make
this same mistake.
