You asserted (or implied) that a Boolean value was insufficiently
expressive to convey the range of possible policies that a captive
network might impose. I asserted that while that is true, whatever
you do will be turned into a go/no-go decision by the UE. This value
is giving the network provider a direct input to that decision.
I acknowledge that you might conclude that we're back to gaming this
out, but I have heard UE vendors say that they really don't want to
probe. So if the network says that it's good, I think that they will
save the probing for when the network breaks instead. But we'll let
Tommy and Lorenzo respond.
