I don't see how an AM4+ would make things any less confusing than they already are. If they did an Am4+ then AMD would have to design another line of Zen CPUs called Zen3+ just like what they did with Zen+ and the 2xxx CPUs. AM3 and AM3+ weren't that confusing because all AM3+ did is added AMD FX CPU support. Also AM4 has 3 Generations of CPUs so far soon to be 4 when Zen 3 launches. So adding an AM4+ would make stuff even more confusing than it all ready is. So you are wrong that it will solve any of the misunderstandings.
