Thanks for the valuable feedback. I've read the links you shared and 
tried to get a big picture. Here is what I'm thinking about this.

time, so the plan is to publish css3-page Soon® without much more 
features than it currently has, and start in parallel with css3-page.

I don't have much experiences with how specs are written and how they 
evolve. Does the time a spec is worked on has any direct implication on 
the quality of the spec and therefore then older the spec gets there is 
no way to change it anymore - even although it's not official yet?

If I get this right, css4-page builds on top of css3-page. By using new 
standards (I think the regions spec was mentioned here) the css4-page 
spec might be able to solve my problem of inflexible margin-boxes as 
raised in point 1). Lets assume for now that css4-page will solve my 
problem 1). But then I don't see why there is a spec for fixed 
positioned margin-boxes as defined in css3-page and one iteration later 
in css4-page it's possible to define them more flexible? This looks like 
more work for implementers to me as they have to implement two somewhat 
redundant specs that define the position of the margin boxes on a page.

The running element spec looks very similar to my idea of using "position: pagebox" here. However, the running-element spec looks more complicated to implement compared to adding a new "position" property option. Do you have some key points why the running-element could not be replaced by the "position: pagebox" idea?

Very best,
