While we are all operating under the same strict rules, it is my impression and experience that some non UK/USA airlines will still allow cockpit visitors.
Personally it makes sense, the USA has had a no-cockpit-access rule for the last 20 years, it failed to stop 911.......
Now each flight has between 100-400 active skymarshals, so hijackers with a stupid little knife havent got a chance.......
