If we put (say) .webp into auto-mode-alist, but we can't read .webp
files, then image-mode will end up issuing an error when called on these
files.

Besides, what formats "gm convert" supports changes over time.  By
consulting it, auto-mode-alist will be automatically updated without us
having to do anything.

Yup.  I meant "do nothing" in the image-mode context, which means "show
the data as raw bytes and signal an error".
