I agree. I've ridden a number of miles on gravel rail trails with 28 mm or 1 1/8" tires. I'd probably pick something a little bit wider if I was building a gravel-specific bike, but those worked fine for bikes I use on both pavement and pea gravel. Not once did I think during my trail rides, "I really need some wider tires."
