yes, but it is still true that there is a cost for the client and for deployment of non hash based URIs, since they require 1 extra dereferencing: ie. one more connection on the network. The speed of light being limited, this is a cost. 

I would change the "can have impact on performance" to "have impact on performance".

Perhaps "highly encouraged" can be reduced to "encouraged". In any case we need some reason 
to explain in the spec why the examples are in terms of hash uris.
