SO, things may change in the future. That's an astonishing insight.
I think things are changing now. Recently I went on a domestic trip to a conference that I had previously gone to last year. The food purchase area at the conference venue had a PIN pad attached to their standalone terminal which definitely supported contactless. Last year, that PIN pad was on the cashier's side of the counter and the cashier inserted for customers. (You probably could have used Apple Pay there last year but I'm not sure how much of a pain it would have been to convince the cashier to let you try.)
This year? The PIN pad was on the customer's side and they specifically had people wait until they could enter the amount on their end (which is necessary to enable contactless for some reason), assuming that people would tap their cards instead of inserting. Most people tapped their physical cards, of course, but the fact that it was made easy to do meant that Apple Pay was just as easy to use.
In any case, it'll be interesting to see what the stats are next year when Visa releases them.
