Sort of funny because the 1x system isn't really new technology. If anything, it's a lot simpler with less parts to break than a traditional FD system that a tourer would use.

A large cassette is the same tech as a small cassette - it's more of a new implementation of a proven technology. I suppose you could say that a clutch in the rear derailleur and the narrow-wide chainring are "new", but they've been used for many years in the MTB world so in my mind they are both proven and readily available. In other words the 1x system would be less likely to break on tour and also I wouldn't need to worry about finding FD parts in a remote area.
