We just lifted a restriction to allow a 3rd alternative.
You can now declare 2 ports with the same number as long as the protocol and the port name is different.
It allows you to have 2 urls http-xxx and grpc-xxx that point to the same port but with the correct protocol set for each.
This is as far as we can get, if you need the same URL for the 2 ports it will not be feasible for now for us.
