IMO, there is a lot of experience to be gained by having only one lens with you and finding ways to make it work in whatever situation you are in, depending on the focal length of course.
In my younger, poorer days, I had only a K1000 and a 50mm lens, which was replaced by a 28mm lens after the original was stolen. I used that combo for decades, and made many good pictures, and a few great ones.
Even in the last 48 hours I was using only an FA-77mm and taking a lot of pictures, and I really started getting a feel for it, and then trying new ideas in order to maximize its abilities. In December it will be my SIC lens and I'm looking forward to it.
