And as far as I remember:
The radar controller is only responsible for obstacle clearance after having pronounced: "This will be a radar vectoring for a final ILS (or what else) approach for runway ..."
With almost 5000'/min rate it takes a little more than 4 minutes to get down from F360 to 14000'; it's not such a long time to... "Aviate, navigate, communicate" & "Dive and drive"!!!
