Essentially US airlines' conception of in flight safety is primarily a toilet obsession. people trying to use the toilet in a different cabin (which I don't like people doing but still) will be seen as a major safety risk, and FAs will build a credible replica of the Berlin Wall using food trolleys every time a pilot wants to pee or chat with them in the front galley or whatever.
I've been on BA flights where they have allowed people to use the washrooms when the belts are on. My mum is pretty old and we had a long time on our last flight together and she was desperate, I pressed the call button and the cabin manager said it was fine provided we understood it was at her own risk.
