But neither does Emacs.  So there is no sense in Emacs making it more
complicated for the user to display an image.

That's their problem.  And Emacs _can't_ be wary of images since its
knowledge about potential library problems is fuzzy and much weaker
than that of the library authors.

So Emacs can't help users to learn in a sensible manner.  It can, at
best, disturb them.
