I'll never understand how this topic can generate so much discussion. Whether you use QFE close to an airfield or in the circuit, or QNH all the time, makes precisily no difference. In the first case you need to remember to reset your altimeter now and then; in the second you need to do a little mental arithmetic. Neither is a big deal, and it comes down to personal preference.
But if something like this is changing in any way, it would be nice to be told, particularly for instructors who are passing on this kind of stuff to the next generation of pilots. And this is the first I've heard of it!
