Nope, the lesson hasn't changed, and the first item on my checklist prior to the run-up after applying brakes is "Position into wind, check clear behind".
Poor airmanship is everywhere, from flying through well-used instrument approaches without talking to anyone (apparently "OK as I'm in Class G"), piss-poor RT (umm, err, umm, hang on, err, not sure what I'm doing, err...), transmitting over each other, etc.
I was taught to do checks at the hold unless that causes delay to other traffic, in which case another better-suited area if available is chosen - again, airmanship.
