CIRAWFilter.supportedCameraModels(with: .version9) does not include camera models that appear to be supported

CIRAWFilter.supportedCameraModels(with: .version9) does not include some camera models that appear to be supported.

For example a Sony A1 or Nikon Z8 RAW file opened using CIRAWFilter and then calling filter.supportedDecoderVersions.contains(.version9) return true but these models are not included in the supportedCameraModels list.

Why is the supportedCameraModels(with:) not all the supported camera models ?
