I don't think we should go to far to correct this bug in
implementations. My understanding is that this have been observed but is
not a common behavior as these generic ALGs do break things randomly and
horribly. I would only do something about if it has no minimal impact on
the specification and any deployed implementations. Otherwise the fix is
likely to cause more grief than the few devices that are broken.
