Actually, CAA has no say in the on-board arrangements of foreign aircraft, which are the responsibility of the body issuing the operating licence. Thus why UK airlines are fanatical about opening blinds for take-off landing, but others using UK airports may not bother.
That said, there are international bodies which do have a say in setting minimum standards, and I could see national bodies like CAA lobbying those to try and ensure this wouldn't be allowed at an international level.
