Not that rare, especially for text-based image format, or to view/edit the
text in the header of a non-text image format.

I admit that I've never opened a png file in Emacs, so for png it might be
OK, but in general there are several "image formats" which are quite
viewable/editable in Emacs.

OTOH I find auto-image-file-mode of very dubious utility: you can barely
look at the image (it's a bit better now with partial-line scrolling, but
it's still much more clunky than any other image-viewing tool), and you
can't do anything more (crop/zoom/rotate/save in another format, ...).

Agreed.  `auto-compression-mode' should be ON by default.
