Accretion of features should be preferable to breakage. I think most people, particularly those using Go, would agree with this. It does not follow that we should make breaking changes easier or routine, nor that we should force people to use strict semver (which is not widely used for good reasons). I see why they've done that as it simplifies assumptions but prefer the way other package managers handle this where it is left to producers and consumers to negotiate how strict they want to be.
