This forum is a User-to-User forum so no one here knows what plans Apple have - if any - for adding support for a particular model of camera. As I said above:
To be blunt, adding raw support does not seem to be a priority these days for Apple. So, some cameras are never supported, so partially supported and some fully so.
Options: Convert the raws to DNG with Adobe's free converter.
or
Use a third party app to manage these (and if you wish) all you photos. Apps like Adobe's Lightroom and Lightroom Classic, CaptureOne, DxO Photo Lab, Mylio and others have their own raw support and tend to be faster and more complete in the support they offer, but then they ought to be as you pay for them. Also consider the software that the maker of your camera recommends, which is most likely free and there are also open source options too.
