But image-jpeg-p exists, and has been used in image-type-regexps, since 2001:

2001-08-08  Gerd Moellmann  <address@hidden>

        * image.el (image-type-regexps): Allow predicates.  Change the way
        JPEG images are recognized.
        (image-jpeg-p): New function.
        (image-type-from-data): Handle predicates in image-type-regexps.

It was, apparently, never intended to be anything but a helper for
image-type-regexps.

The discussion you're talking about is much more recent, isn't? (2005
or 2006, I think.)
