What's the approximate cost of those scan chains.  I.e. if we were to
take an existing working design and replace all the "flip-flop with
scan-chain" with "plain flip-flops", how much smaller would the
resulting chip be, how much faster could it run, and how much less power
could it consume?
I wouldn't matter because it wouldn't be testable in production.
