I very strongly feel that these issues need to be sorted out before CSS3
Regions makes much progress, and ideally before it's even implemented. I
don't think "CSS3 Regions" should depend on "CSS4 Paged Media" --- it would
sound weird for a CSS3 module to depend on a CSS4 module.

It would be pretty easy in Gecko (and I suspect other engines) to implement
the core of CSS3 Regions (and CSS 2.1 page sizes) and get reasonable and
interoperable behavior for some common cases where containers have different
widths, but get wildly wrong and/or non-interoperable behavior for other
cases. Then we get to spend years negotiating implementation differences,
fixing bugs, and worrying about compatibility with deployed content. Let's
not dig ourselves into that kind of hole again.

"Now the Bereans were of more noble character than the Thessalonians, for
they received the message with great eagerness and examined the Scriptures
every day to see if what Paul said was true." [Acts 17:11]
