NIST's comments suggest that the defense suggested in 6.2.3.2
should be  mandatory. My argument is that hardware systems may
operate in fixed time or otherwise be safe and so we shouldn't
mandate any particular defense.

Perhaps we should mandate it for implementations that are vulnerable?


Proposed resolution: leave as-is.
