Historically, it was a mistake to allow A..B to be used for two endpoints, which was made back when we haven't thought things through. That is why I stopped "warn to deprecate and then completely remove", as I do not think it would help people very much if "git diff A B" can be spelled with two-dots. But in a distant future long after that happens, by the time nobody remembers what A..B meant for "git diff", I do not think I'd strongly be opposed to reusing it to mean something different.
