The "special_features" field / parameter holds the subset of schema features that are for internal code use. Specifically 'DEPRECATED' and 'UNSTABLE'. This special casing of internal features is going to be removed, so prepare for that by renaming to 'features'. Using a fixed size type is also best practice for bit fields.
