Yes, but you don't want all that behavior to be reflected in the  
decision tree in your TCP implementation.

Would it be possible to specify a single behavior that is simple,  
provides the intended benefits in the common cases that compromise 90%  
or more of all cases and doesn't do worse than what we have today in  
the remaining cases?
