The important part there is "most networks".

What about a network that is not one of "most networks"? My point is that 
one size does not fit all, and that "most" != "all". So I think we need a 
policy that applies in the general case, a policy that applies in specific 
cases where the general case doesn't work, and a rule for saying which 
policy applies.
