I assumed since he was asking about a "top of rack" (TOR) switch, he was actually using it as a top of rack switch and adding a couple more uplinks to his core would be cheaper than replacing all the hardware.  Not understanding the topology and the application makes good recommendations a crap shoot, at best.

In the case of a tor switch, the use case is typically in a situation where you're not downstepping from a higher speed to a lower speed, and where you don't really need fancy qos.  So as its not generally needed for the sort of things that tor switches are used for, its not added to the hardware spec.
