Maybe it's just the airport I was flying out of (LGA), but I noticed that the TSA signs explaining the millimeter-wave scanners no longer say that you can opt-out of them. Where it used to say (IIRC) in smaller print at the bottom that you could opt-out and get a manual pat down in a private space if you so chose, there was now boilerplate text about how there were no health and safety risks associate with getting scanned by the machine, and that it wouldn't produce a photo-realistic image of me. Once I opted-out by walking to the metal detector and (after being told to go into the other line for the L3 ProVision unit) asking for a pat-down, the agents handled it as usual (a bunch of awkward shouts for a "male assist at station 3", an embarrassed guy walking over and asking if I knew how this process worked and had done it before, and then a pretty perfunctory pat-down) - but if I didn't a priori know that I had that right, it wasn't listed on any of the many signs in the security scanning area.
