asymmetrical routing in the first place?

For any non-trivial path, it seems to me that asymmetry in forward  
and return paths is normal. Symmetrical paths are the exception.

From another angle, how can anybody hope to ensure that all forward  
and return paths are identical when the only exit under their control  
is the one on the outbound path, at their own border?

If this is for their customers, it wasn't clear that the path went
outside their zone of control.  I did wonder.
