Low Risk
127 is the last network number in a class A network with a subnet mask of . is the first assignable address in the subnet. cannot be used because that would be the wire number. But using any other numbers for the host portion should work fine and revert to using . You can try it yourself by pinging if you'd like. Why they waited until the last network number to implement this? I don't think it's documented.
