I don't understand. In either case, nothing can be fixed in the
hardware after it enters the box.

This can be said to pretty much every ASIC/pipeline box, they can't do

This is certainly part of the reason vendors don't want to communicate
openly, if customers decide product is inferior based on the logo on
the chip. I guess same reason why they don't document clearly the
limitations, they know that lot of customers won't actually use the
boxes like that, but might not buy the box out of fear if the issues
Vendor's openness depends on customers doing informed, fact based decisions.

It can't be manipulated after the hardware has been made. It does what
it can do.

Are you implying Cisco would say to you they don't give you feature
and forwarding performance stamp of approval to ASR9k, because it's
not their chip? If this is the communication you receive, I can
understand your position.
