When I was learning go there was a certain disdain among amateur dans, which I picked up, for the attach and extend joseki. This was not because of the later one space jump, which most people had learned not to do, but because a lot of kyu players always played it, without reflection. The most popular dan response to the keima approach was the simple one space jump, which, truth to say, was also usually played without reflection.
As for the "new feeling" that Takagawa talked about, perhaps it had to do with the fact that, according to magazine articles that I read, one space jump attachments were becoming less popular in joseki, because the strength gained from them was not as good as the strength the opponent gained from the hane in response. Most of these cases, as I recall, were underneath jump attachments on the third line, which were being replaced by the slide to the second line.

Yes, when Black already has an extension on the side, maybe otherwise.

Yes, it's definetly on the list of candidate moves to consider, indeed bots do fairly often think it is BETTER than the hane. Here's a video from Yeonwoo about it.
