I'm confused, my neighbours have been doing this since March - and I'm talking about more than one street. What Boris is saying now is pretty much what our whole village has been doing since March. As long as they are outside or in the garden, they do as they like and friends and family come over. They don't do the 2 metres either; outside is safe as far as they are concerned.
I think a great many people have been doing this all along.
