I think the underlying motivation for [5] includes (at least) that:

 (a) the use of regions encourages creation of extra markup for
 stylistic purposes only, which is inconsistent with separation of
 content and presentation

 (b) the model of creating elements to be regions is inconsistent
 with the typical model of writing CSS where new property
 declarations cause observable changes, without requiring a
 complicated set of declarations and content changes to achieve an
 effect

I don't see how the above addresses these problems.
