My two penny's worth.
Crown is all about concentric. Recess protects the crown where the bullet leaves the barrel. Off concentric crown will push the barrel this way or that. A pitted rifle barrel will not. The Crown will. IMHO, The Crown is a big part of accuracy. Bedding a rifle action is a very small part. In best rest, every 0.0001 improvement is a must.
When I re-crown, I like reset. It protects the crown.
