The single motor driving multiple screws is a very workable and much better approach than using multiple motors. If someone previously abandoned the idea due to "slipping", they made a big mistake. Keeping multiple motors synced is a problem. Keeping multiple screws synced with one motor is easy. The real reason it isn't done more is because adding a second motor is cheaper than adding pulleys and a closed loop belt, and cheapness is king in the 3D printing world (at least in the US).
My printer has had two screws connected by a single belt for years and has always worked perfectly. The only time I've ever had to adjust the X axis is when I first set up the machine and on rare occasions when I've taken it all apart to make major changes and then put it back together. I have actually taken the X axis off the machine completely and put it back without having to make adjustments (because the Z screws stay in sync because of the belt).
