Over here (Scotland) we are quite often given a squawk to wear and
provided (without asking) with a deconfliction service.
This is in busy corridors.
ATC will then keep commercial traffic 3000' vertically from us, usually
over.
We don't have the busiest skies in the world and half of me thinks the
controllers do it for their own interest to make it easier to keep up with

our antics on the day.
