The boarding at T5 on my MAN flight a couple of days ago was astonishingly well policed. The usual huge priority queue was present but after pre-boarding (replete with a family of 12 Somalians who would appear never to have travelled by plane before) completed, it was BUK and Gold only and boarding passes were inspected to proceed. That cut out a lot of the queue for me (although I did here a few people whinging about having flown in F etc. etc as I passed them).
My earlier flight from DUB had similar announcements but less proactive policing of the queue.
