The side effect of using this list approach is the loss of the Quality option on the Convert action. I was able to select random RAW images (DNG, RW2, NEF, etc.) and convert to image types from this list. If a RAW format is not supported by Apple, then the conversion will still occur to an image you cannot view in Finder, Quick Look, or Preview. Just tried this with a Nikon Z8 NEF with the preceding predictable result.
