So the "3.0 _only_" case ends up being a fairly rare case where things have been explicitly limited, and any previous Linux use must have had that explicit "vers=3.0" flag anyway? No? Anyway, we can't avoid *some* breakage (ie the places that literally only support 1.0 will have to add the explicit "vers=1.0" to get the mount). And I merged the code to add better error reporting yesterday, so hopefully regardless of the default we choose the breakage is not nearly as confusing to people any more.
