Note that EAC is trusting the drive more than cdparanoia is; there are
plenty of drives for which that isn't true.  If the C2 information
returned by the drive is wrong/fabricated/missing, EAC will never know
there was a problem.

On drives that return trustworthy C2 information, EAC does use the
information effectively.
