WDYT: Since we are otherwise just blindly inserting this string into the `ecs.version` field and it comes from an external source, is it worth performing some sort of validation here so we can fail with a useful error message if something unexpected comes back? Could be as simple as a [`semver.valid`](https://github.com/npm/node-semver) check.
