> nowadays raw (or indeed the ever-shouting all-caps “RAW”) is primarily a marketing term used to denote lossily processed data left and right (ProRes RAW, BRAW, Sony’s “raw” .arw files that in fact come lossy from some cameras)

That does happen but I don't agree that it's "primarily" used that way. Canon and Nikon are still dominant and still use it to refer to uncompressed raw images.
