Is there a reason for keeping areas from absolute and fixed 
block-containers in the flow of normal areas?

IIUC absolute and fixed block-containers generates areas with an 
area-class of xsl-fixed and it is hinted that such areas is taken out of 
the flow and placed under the page-area:

""" [7.5.1]
Absolutely positioned areas are taken out of the normal flow.
...
The area generated is a descendant of the page-area
"""

If I'm right about this, the break-out code can be avoided by placing 
the absolute and fixed block-container differently in the area tree.

You're right, but it didn't occur to me at that time. Another thing to
look at when we talk about this would be z-index. I assume this would
play into the same corner.

Well, another thing to keep in mind while we make progress. I'll make a
not on the Wiki.
