This has been my feeling from the beginning, so I'm happy to support
this position.  I think the current version - where scan-ability is
tracked in just one way - is an improvement over the previous version
of the patch - where it was tracked in two different ways with a
confusing shuffle of information from one place to the other.  But my
favorite number of places to track it would be zero.
