But now take note of the strong white positions on the outside of the shape:

White can surprise black with this alternative if there is such strong support on the outside.

Just be careful. The usefullness of this alternative move depends a lot on the surrounding position.

Not
all , there was a Go Seigen game in one of JF's books where they (can't recall if Go or opponent, but probably Go) had the hane resistance, or at least it was talked about in the commentary. But yes, it is an alternative we shouldn't neglect to consider, and pros probably do suffer from too much autopilot. However, there could be a selection bias in that if the hane is a good resistance and black is aware of that he won't cut in the corner but immediately play the 2nd line descent.

Good old Go Seigen, always a pleasure to meet him again.

Just to be clear. My intention is not at all to disrespect the Pros. I just post because I like unusual moves. A usual move would be of less interest to me, as it is already widely known.

In my 105.000 game database there are two more games with this move and the 4th line expansion (and 3 with the third line expansion).
This is one of them:
Fan Tingyu 9d - Motoki Katsuya 8d, W+Resign (Komi 6.5)
