This path includes xx, which contains the major and minor numbers. So
adding "semver" would only allow accommodating different patch levels.
Would that be useful? Different patch levels are supposed to be about
bug fix only changes, so there's usually very little reason to carry
anything except the latest one for any specific major.minor combination.
