Pure speculation, but I'd imagine support will be added in the future.

Assuming implementation is similar to that on the cat6/sup2, the biggest
problem will be the 1/2 reduction of tcam entries. On that platform its
pretty painful going down to 128k entries, but on the cat4, that would
take it down to 64k.
