OK yeah, so then for printing profiling targets, simply use /DeviceRGB or /DeviceCMYK or /DeviceN and not specify an OutputIntent. And then do not make assumptions when rasterizing (i.e. better to fail on raster than to make assumptions)

Unfortunately for Apple, such a PDF always gets a source and destination profile assumed when rasterizing - it should be the same profile assumed for source & destination, ensuring a null transform. But that is a very convoluted way, it seems, to get the intent of what the PDF is saying by the way its already written.
