Suffice to say that they do not recommend against engine braking--quite the contrary. Think about it: the engine is already spinning, so spinning it at a higher RPM for a few tens of seconds does no more wear than accelerating.
The issue is not brake wear--the issue is brake fade, and potentially boiling your brake fluid!
When you're going down a long hill, downshift and save your brakes! It could save your life!
