I'm sure there must be a good reason, but I'm blowed if I know what it is.

There is no good reason to Keep QFE going there are good reasons to get rid of it.
Often aviation is steeped in tradition on the principal of this is how its always been done.
The overhead join another example from the past when aircraft had no radio, needed to see the airport details, needed to make sure they were over the right airfield etc.
I am against QFE because it adds another point of confusion. Flying IFR we use QNH only! Most of the world do not use QFE and there is a potential dangerous mistake in the making having two altimeter settings operating near the ground.
