Thankfully, context clues let us sort these things out in the vast majority of cases, but there is some small cognitive load there. I do think alphabet being called that poisons the word, in that it creates opportunity for ambiguity. It's another wrinkle in an already messy language that's mutating and forking on multiple fronts. No cap, I'm finna stop alphabet-wannabes yoinkin muh words, it's annoying.
