Interesting. I can only speak for FRAports Terminal A where the Lufthansa flights go and they use the new bag scanners where I just need to get rid of my coat and belt to be scanned by the infamous "Nacktscanner". The first time I went through I thought liquids were allowed from all airports in the EU until I found out it was bag scanner dependent. Smaller airports are usually OK because queues are short and then I have the time to walk TSA through each individual item personally. FRAport has started adopting the "snake-through-duty-free" before the gate (pioneered by Stansted as far as I can tell) which is criminal in my opinion (it's not as bad as Stansted yet). Commercial workflows are thus not always better when the optimize time customer has to spend "not buying" overpriced meals and consumer garbage.
