HEIC is a bigger problem than JXL as there are enormous royalty payments, slanted in favour of multinationals like Apple (i.e. high per unit fees, but with a large but flat maximum payment). I’ve personally tested processing HEIC photos vs processing JPG conversions from HEIC. There was no difference in quality. HEIC has technical potential but current iPhones are not using that potential. Resurrecting support for the conversion of iPhone DNG on the other hand would make a huge difference.
