miniSAS active cable keying

During our last SAS phy conference call, there were separate keys 
indicated for active cables (see 08-257r0). I am wondering what the 
implementation plan is. The keys provide no protection from plugging in a 
SAS 1.1 (legacy passive) cable and the phy's should work with the SAS 2.0 
10-meter passive version, so what is the advantage of adding this key? I 
guess I am missing something in the planned implementation. Could someone 
elaborate?
