As for how it will work for a major? Same way it does at any other course, the pro's caddies will be out during practice rounds with yardage books stepping and lasering distances from every notable object. They'll probably have a hand drawn map of every sprinkler head and its yardage. Just because they can't use those devices in a round of play doesn't mean they won't be all over the place during practice. They'll have plenty of accurate yardage references.

For each round, player and caddie will walk about five miles over Merion's fabled East Course, where not only motorized carts are banned but also electronic distance finders, GPS locators, and other gadgets that are now part of most courses. Moreover, on other courses every sprinkler head carries the distance to the next green; at Merion, there are no yardage markers anywhere. That information rests exclusively with the caddies, who are expected to know how far it is to the green from any point on the 126-acre course.
The article says that devices for "lasering" distances are banned. They aren't even allowing Walker Cup players to bring their own caddies. The Walker Cup is run by the USGA, just like the U.S. Open. If Merion is unwilling to bend its rule for the Walker Cup, what makes you think it will acquiesce for the Open?
Again...during PRACTICE rounds, I would expect the caddies to be using every device they want to measure anything they want. I wouldn't be surprised to hear a pro's caddy hired a local caddy to walk the course with him in order to get the best notes possible. As far as I know, there aren't a lot of rules for the practice round. Once they're playing the COMPETITIVE ROUND, then they may rely on the caddy notes. I would guess even at the Walker Cup, the players may walk the course early in the morning to measure distances and mark their notes OUTSIDE OF THE ROUND OF PLAY.
Really, banning any of the devices at the PGA level would make little difference. For example, I'm sure Callaway would be glad to take every useful piece of data from the satellite photography they use for uPro maps to build a paper coursebook with every yardage (including every sprinkler head) and all the pertinent slopes to aid their sponsored players. From what you see on TV coverage, caddies seem to rely on their notes and stepping off distances more than any other devices anyway. When you consider everything these players and companies have on the line with every major, you can be assured they're not going to be blindly guessing any yardages.
Seriously, you don't think Merion will bend its rules for the USGA. They absolutely will. In fact I would pretty much guarantee their agreement in hosting the event gave the USGA complete control over the rules of play for the week. I'm pretty sure the pros brought their own caddies at the 1981 Open. If the USGA wants to add a bunker or two, I wouldn't bet against it. Want to make a par 5 into a 4 for the week? No problem. I'm also fairly certain the grounds will have plenty of motor carts roaming about with TV crews, VIPs, and rules officials. And given that it's a private club, I'm guessing they may even boldly waive the requirement that all guests play with a member.
Outside of the Open. I really think the unmarked, use a caddy system would be fun to play. I don't think it really results in a more "pure" golf experience than playing a marked course. And, personally, the cost of using a caddy every round is out of my price range. But as a concept, it does sound like a nice twist. Kind of like the wicker basket pins, it makes it a little different - a bit harder to read the wind - but doesn't really change the game.
