I’ve used this a few times already and it works perfectly about 80% of the time. If your picture has a lot of grain or low-level noise it’s just going to make the noise worse, then you throw in a median to de-noise and you’ve lost the benefit. But it’s otherwise a nice tool to have, especially for older low-res photos (like 800x600 stuff you want to print).
I think longer term stuff like neural rendering will make super resolution less relevant. If you can re-create a 3D scene from a single photo or otherwise reconstruct the photo in a less-resolution-dependent way, then playing the super resulting game is less interesting (for users and researchers alike).
According to TFA, camera raw isn't required to use "Super Resolution", but regardless the answer to your question is "people who cropped their original photo".
I can’t get the Enhance feature to work without using the Camera Raw plugin, but yes it does work for ordinary jpegs and such. You have to open the file through Bridge. If you open Camera Raw through Photoshop (in the Filters menu) then the Enhance option doesn’t show up :P
