I think not being able to use the front lav and no corkscrews *is* too severe. All the new "security" introduced in the last weeks (with the possible exception of banning 4" knives) would not have stopped what happened on 9/11.
Keeping the seatbelt light on in this case could have been related to weather, and I accept that as it happens a lot.
Banning cutlery and people form using the front lav is dumb.
