Perhaps yes, but perhaps a social indicator that I am doing something and have requested not being bothered, should be enough to discourage the people who just can't wait to ask you questions and converse with you. In that, extroverts are like little children: pay attention to me, pay attention to me, I have something so important to tell you that can't wait, and I don't care what you are doing at the moment, attention needs to be on ME. NOW I'd say, let's normalize scolding people who ignore obvious social cues and bother you uninvited. How about that?
