"Based upon HTTP" is a phrase that's introduced in the referenced section; changing it removes the meaning.

See revision.

Moreover, "The usage of unknown ports can be made at deployment time..." instead of "This decision can be made at deployment time..." and "In either case, unknown ports will need to be reflected..." instead of "In either case, non-default ports will need to be reflected..." speak the same voice than Point 8.

I don't think that these changes are improvements.
