In which case they will get an error message, as in the case when they
try visiting a PNG image without libpng compiled in.

I don't think this is a problem, we maintain auto-mode-alist all the
time.

Why would a user want Fundamental mode for an image?

Wouldn't user customizations override the default value? I think they
would, and then this is not a problem.

Some of the formats are already supported ("svg", "png", "xpm", etc.),
so they shouldn't be added again; others seem inappropriate or
irrelevant ("http", "file", "ftp", etc.). As for the length of the
list, I don't think we should worry: the default auto-mode-alist has
188 elements in Emacs 27, so a couple dozen more cannot do much harm,
I think.
