This might just be my perception, but if I get a puncture that loses 5-10psi, I whip out the pump and add 5-10psi while being thankful that the tubeless system allows me to do that without having to take the wheel off and replace a tube.
I would also think most flats you'd get on a tubeless tire would deflate slowly enough for you to come to a stop before the bump becomes an issue (if it even does). That's including a gash on the tire that spews sealant like a fire hose.
