It just accidentally has an effect. The type of that property is Predicate<ProfileRequestContext>, and we have converters that turn true/false into predicates.

Can you please file a bug? We should be more explicit if we can and block use of other values.

Being forgiving isn't strictly speaking an error but it's not helpful here.
