One of the big reasons I don't get Peter's caution is that anywhere I've ever worked, nobody has upgraded Boost more frequently than every two or three years, and it's usually a lot more. Maybe I've worked in the wrong places.

This might well be true in a corporate setting, but downstream packagers such as Linux distros, brew, vcpkg etc "upgrade" Boost more frequently (on each release) and every breaking change in Boost typically affects (many) other packages that then need to be fixed.
