Maybe we want to do this and maybe we don't. One idea is to have all features have a standard pattern/class for the fields. This would contain the metadata version mapping and a Map<String, Short> of the required other features. Not sure if we will need any more complicated validation logic than that. We could leave the opportunity to have a more complicated validate method if we choose. We can also show an example implementation in the TestFeatureVersion and folks can choose to replicate it. -- This is an automated message from the Apache Git Service.
