Yeah I figured that CDN providers probably implemented this too. I think like you said before, there are certain situations in which it is good to be able to validate an original image hasn’t changed but I think this needs to be implemented in a way that doesn’t break when clients don’t implement the NIP or of an image is compressed for content delivery optimisation.
