I think, if it’s done correctly and the courses implement it, and I believe they will, that the out of bounds rule can really speed up play. If folks go up to drop where it went in, as opposed to heading back to the tee, where they should have hit a provisional any way, that it will speed up play.
Actually, if I ran the course, there would be no out of bounds if possible. Red stake everything and keep it moving. Everyone plays under the same rules so no one should be complaining.
