No one here knows what plans Apple Amy have for supporting any additional cameras. They add it when it suits them.
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.
Personally I go the 3rd party route. I've never seen the point in spending a couple of thousand dollars on a camera plus even more on glass, and then trying to process them in a give-away app. But that's just me.
