That would be way too extreme, I think. You back up to where the objects of interest (the one in focus) approximately fills the frame. Closer if the object is stationary. Then you just take a standard panorama at your widest aperture. Generally I’ve found once your final image goes beyond 35mm or 50mm equivalent field of view, the panorama fails to merge or the Photoshop function starts to make wacky assumptions about distortion.
Oh shit look at that, it has a name.
