Well, as any road user you are responsible for anticipating.
So you have to both anticipate the slowdowns/overtakes in front of you...and anticipate the people that don't anticipate any of this/don't look and will take you out if you don't shoulder-check when you move to the right.
I agree. Overtake staying wide and covering brakes where there might be non-anticipators obvs.
But I would never move out to the right if I had to expect another road user to slow down for me. They have greater right of way and it's safer for everyone.

It's sort of an anticipate inception.
