They are really impressive! At the very least, a 3x3 nine shot pano could easily be integrated for a great automated 7x telephoto stitch in camera, rendering much sharper detail than a crop of the identical frame area from the automated 360° Pano on the main camera.
Here is an example in bad lighting showing the difference in detail. Click on the thumbnail below to see the noise and pixelation in the 600% crop of the 1x image, compared to the 100% view of the 7x telephoto from the same location. If you can't fly closer, for whatever reason, using the 7x telephoto is the perfect solution, and it also gives a much better compression perspective with distant objects in the background being brought closer together with foreground objects than flying closer can ever do!
