Flew LIS-PHL 10 days ago. The security at LIS was not so much night and day from TSA at PHL but was different. Shoes on, WTMD (I assume they have pat-downs instead of a MMW Scanner at random/for pax that alarm) and electronic devices bigger than a smartphone in a separate x-ray bin.
So any of these "enhancements" (Electronics Swabs, Liquids checks for places that don't already have a 3-1-1 type restriction, ID verification) will probably be done at the gate or CBP pre-clearance if such facilities exist.
