Response to dev vs contrast

It's sorta true. If you develop films to the same C.I., gamma, or slope (all a bit different definitions), then the overall contrast will be the same. IMHO, the appearance of the prints will be quite different, not only with regards to grain, but contrast of details (microcontrast?). Another interesting thing is when people talk about tonal range. Most films seem able to produce prints that go from black to white, so I'm not sure the phrase is meaningful. What does matter is the shape of the curve and where good separation occurs. BTW, you refer to "overdevelopment"- over or under, the curves are the curves.
