Its also very, almost a must, convenient when doing interoperability
testing in some events like upf where we have a lot (annoying) devices
trying to reconnect to us while we are testing with other devices.

@ Johan, Blocked does supersedes Trusted right? Maybe we should rework
those properties (deprecate them?) to something like Authorization
which takes a string where lets say can assume these values: "deny"
("block"), "ask" or "allow".
