Since 3p apps are allowed to use restricted networks in S, they
should be allowed to request a restricted network reasonably.
Otherwise, the functionalities of 3p apps will break if they rely
on restricted networks. Thus, CS needs to allow 3p apps to
request restricted networks if 3p apps are in the allowed list.
