I case that wasn't evident from my post, I don't mean that requirements 
propagation should be default behavour. It should be some special kind of 
requirements

lib my_lib : ...........
: <export_include>.....

Since, for ill-behaving libraries, you're likely to write Jamfiles yourself, 
it will be possible to decide is exporting include is needed or not.
