In the UK we donīt see this, because itīs not in the Schengen agreement, and as such, everybody coming from abroad has to go through security (not immigration, as docs are checked at the gate by airline staff).
I don't think this is completely accurate - from past experience, and by having a look at the flight connections pages on the Heathrow website as an example, unless you come into the UK internationally and transfer to an international flight, you do have to pass through immigration.
