One problem with a tubeless road tires and big cuts is that they're flat in less than one revolution so you need to have decent bike handling skills. I've also had cuts that were so bad I had to tear a piece of bar tape off to cover the hole so the tube wouldn't stick out.
MTB tubeless is almost a must have these days. You can run really low tire pressures for traction without fear of a pinch flat. If you're far from home, vehicle or support you just carry a tube.

Interesting regarding the sudden loss of air in the road tires. I always carry a "boot" cut from a plastic milk jug to address the big gashes.
