When we started playing with FDM. it was "stabilized by 1000AGL"
We said "Fine, but what we'll do with 160, gear up and half flap till 4 miles out?"
There was a pregnant pause.
Now it's still "stabilized by 1000" but with if ATC procedures so require it's "landing config by 1000', power and speed by 500'. Not applicable for non-precision approaches."
Everyone happy.
