The fact that a lot of Telco and some other sectors use reduce depth racks to begin with?
there are many many applicatitons of reduced depth racks that pre-exist, we see this a lot
when we install equipment in telco sites - full depth simply is not available, or is restricted to certain areas of operation.

Its not a matter of advantage, its a matter of standards.

Of course, in many other applications, that does not matter.
