I think this is a bit of a 'non' thread.
All that is changing is that in the spring- so we're talking march-April, the law will change. It was still be a recommendation to isolate if you are positive, but not legally enforceable.
That seems reasonable to me.
At the moment people have to isolate BUT how do we know they are anyway? No one is policing that. And PCRs are no longer being used, just self-administered LF tests.
So IMO the law is just catching up with current behaviour.
