If it's so horrible why is it in 21.1.14?

image-mode is in the packages, right? image-mode problems are
unrelated to the release. Show me that it's fixed, and I'll consider
a patch to format-alist.
In any case, we have _no_ labor committed to doing the things that
"should" be done, and we have a strong consensus for release. So I
did. The release _is_ "public"; I'm not going to take it back now.
The criterion for promotion from "gamma" to "stable" is exactly that:
don't crash, don't destroy data. "Working image-mode" is a feature,
and IMHO lack of it should not delay promotion to stable. (But that's
mostly Vin's decision.)

Something should be done about that, but there are far more important
things on my personal todo list, like teaching custom about Mule fonts
or at least documenting how to break one leg of `custom-set-faces'.
In any case, AFAIK the image-mode functions autoload, so just do M-x
image-mode.

Sure. But that mode allows a lot more than just detect and display,
and it was silently trashing some files or something. It wasn't just
randomly removed from that alist. It assaulted somebody and was sent
to Coventry for its crime because nobody was willing to fix it
properly.
If you want to add it to 21.5 and see what happens, fine with me[1].
Eventually I'll look at the file(s) and look up the threads. But for
21.4, paranoia rules.

principles.

Because 21.1.x is long since frozen. This isn't a critical bug, it's
just a pain in the neck whose elimination should wait for a new
release, namely 21.4.
As Hrvoje points out, it's not "horrible," it's simply extremely rude
to certain kinds of users. The problem is that it does not use the
higher-level interfaces designed to provide the convenience for users
like you, and minimal obstruction to users with more complex needs.
An explicit decision was made to default such "rude" features "off",
and besides the image-mode autoconversions jka-compr and many Mule
character set conversions[1] (at least) have been defaulted to off in
21.4. Teaching them manners, and possibly reenabling them by default,
is on the agenda, but we so far have rarely gotten complaints. We'll
see what happens now that the code base is publically released.
You can workaround for now by adding
(setq format-alist
(append '(image/jpeg "JPEG image"
"\377\330\377\340\000\020JFIF"
image-decode-jpeg nil t image-mode)
'(image/gif "GIF image" "GIF8[79]"
image-decode-gif nil t image-mode)
'(image/png "Portable Network Graphics" "\211PNG"
image-decode-png nil t image-mode)
;; XPM files are C program text, and as such should not
;; be autodecoded by default. Uncomment if you like.
; '(image/x-xpm "XPM image" "/\\* XPM \\*/"
; image-decode-xpm nil t image-mode)
;; TIFF files have lousy magic
'(image/tiff "TIFF image" "II\\*\000"
image-decode-tiff nil t image-mode) ;; TIFF 6.0 big-endian
'(image/tiff "TIFF image" "MM\000\\*"
image-decode-tiff nil t image-mode) ;; TIFF 6.0 little-endian
format-alist))
to your init file. Note XPMs are commented out.
I'll add this change and workaround to NEWS, and put a Custom
interface (per Steve Youngs's implicit suggestion) on my todo list.

It would be better to use `add-to-list' rather than `setq', since
`add-to-list' is idempotent.
