By the way, the thing that got me thinking about this was "block- 
align:center". If we had a mechanism that would center align blocks,  
and the centered blocks were larger than their container, and the  
container was set to "overflow:scroll" or "overflow:auto", what would  
be the desired outcome?

For me (as a designer), I would want to see the content still  
centered on the screen, with the scroll button in the middle so I  
could scroll left or right to see the overflowed sides. One thing I  
would not expect at all would be to see margin working on one side of  
the scroll plane but not the other.

I was also thinking that if we had "block-align:center", then we  
would also have "block-align:right", which would essentially align  
blocks in the same manner as when the text direction is RTL, but  
without actually changing the text direction. In which case it would  
be especially strange to see the right margins missing when the  
blocks are right aligned, but not see the left margin missing when  
the block is left aligned.
