It's fine to do this out of the if() clause because :
• If the network newly satisfies a request it is sure to have
it in the list of requests it satisfies
• If it does not newly satisfy a request and there is still
a request with a legacy type that it satisfies, then it
is already remembered by LegacyTypeTracker
As for the VPN, the code always enters the condition anyway.
