draft->recommendation process assumes that there are more than zero (at 
least)
UAs implementing the draft in full. If there are no UAs at all that 
implement
the draft then this draft is just a web page with list of desires. Not more.
So to make it recommendation we need to either adjust it to the current
implementation practice/common denominator or to create very strong 
motivation
to UA vendors to implement it. I believe that process of making 
recommendation
should go in both directions. If we are realists of course.

This particular issue with margins, as far as I understand it,
makes real sense for blocks to be replaced in rows by using float attribute.
That is 1) conceptually wrong and fragile anyway and
2) CSS3 is about to have better and technically correct solution.
