Nadav, I agree with all your ideas. Plus the option of reversing their decision to extend. It will still be challenging to convince clients to move to LEEDv4 if they are just doing LEED because its a requirement. The material credits are optional anyway so I was surprised that the material product availability was one of the big reasons for the extension You can just avoid those credits until there are more materials available in the marketplace that meet EPDs and HPDs.
