It has to be done in vast parts of the world.......
In fact, probably most!!
I have seen a 727 go 100m past my wingtip at the same flight level, and cleared at the same level!, and been seen spiralling up across the windscreen of another aircraft 150m away, which lead to an interesting exchange!! Hello, Carl!
By way of example, 100s of aircraft fly into, and out of, Luanda every day, including now, I believe, BA. They have no radar and haven't for years. Procedural separation works fine, almost, and out in the sticks you just talk to the other aircraft and arrange your own separation.
Hey, the sky's a big place!!
