I've seen a scheme like this used for numbering BOSH stemcells and releases[0]. If you have slow-changing or update-in-place artefacts like sourcecode it will look a bit like a shortened semver.
If, as is the case for BOSH, you are meant to totally replace the previous version, then the numbers advance rapidly. Note that stemcell versions are into the low 3000s.
