Why is that a "reasonable extrapolation"? Copper wire won't corrode,
and rust/corrosion is the ONLY reason that codes require rebar to be
fully embedded in the concrete. Please explain ...

Building codes now REQUIRE Ufer grounds in many jurisdictions for new
foundations. Codes also REQUIRE that rebar be covered with concrete,
usually a minimum of 3" to prevent corrosion ingress along the rods.
So it is reasonable to extrapolate that ground wires connected to the
rebar should not exit the concrete below grade ... <snip>
