Regions don't seem anywhere close to a fundamental primitive --
frankly, they're higher-level and more complex than most of the
other formatting concepts exposed by CSS.  Things like
http://dev.w3.org/csswg/css-regions/#regions-visual-formatting-details
involve substantial complexity (implicitly running algorithms in
other parts of CSS in multiple passes, because of the way flowing
into regions can violate the ordering assumptions of other layout
systems).
