Yes.
Unless by "touring" you mean to go way off the beaten path - like several days between towns, I wouldn't worry about hydros there either.
Really, read enough posts and you'll find people who have snapped BB axles, pedal spindles, saddle rails, seat posts etc etc. All of them very unlikely to be carried as spares. And equal if not more ride-stopping than having one out of two brakes fail.
