All this time, Flying mounts were sold in Blizz Shop and gave them huge chunks of money. So, no, flying was a PROMINENT feature of the game for a very very long time to be called an experiment. It was the NORM, not the exception.
We can actually call the "non-flying" an experiment. Why? Because, excluding Vanilla (because flying didn't exist then, at all), Blizzard has experimented with smaller, patch added no flying zones since Cata. The firelands patch quest zone (can't remember the name now), Isle of Thunder, of Giants and Timeless in MoP and then the WoD fiasco with the constant backtracking on when and how flying will be implemented, the announcement of no-flight in current content (where they thought the results of their experiment were going to be accepted by their shitty PR logic) and the emergence of the Pathfinder compromise after the mass unsubs of players over flight (anyone who thinks they changed their minds over forum protests is totally deluded).
So, in all, they are trying to restrict a formerly prominent feature, just because the alternative (which is design content with flight in mind) is too costly and doesn't prolong their easily made ground content.
