Well if my sister tells me that her last date was 'such of a introvert' I am not going to start a lecture of Jung. However if we discuss adaptation from one way of being into another, discussing the process on self transformation in the terms of the guys who described it first might be helpful. I personally think that the modern use of introversion and extraversion are very narrow, and limit the scope of personal growth.

Sure. And I'm saying that you're probably better off finding other terms for the parts you value. As much as I love, say, Shakespearean English, I'm only going to use it in a context where other people are already familiar with what I'm quoting. If I want to communicate a point with a general audience, I'll recast whatever insight I'm borrowing into something that makes sense to them without extra effort.
