I don't think its just the 7500. There's plenty of examples of supported
features becoming unsupported because of "bugs" in the hardware.

Eg: The Cisco 3550 12.1 vs 12.2 MQC policy map matching rules; I think
the 3550's even did netflow at some point(!); the Cisco PXF based stuff
becoming "unsupported" because (and I'm semi-quoting from memory here)
they couldn't resolve all the bugs?

Who bought NPE-G1's and got pissed off that you couldn't really use
the second CPU even though Cisco kept saying it was groundbreaking? :)
