Having a description of auto-sizing seems useful. However, the number
one concern that I and others have expressed over regions does not seem
to be addressed: auto-generation of elements. That is, the regions
spec still seems dependent on having tags in the markup or generating
elements through scripting. Until this concern is addressed, I don't see
much point in reviewing other parts of the regions spec.
