To continue this:
The video and audio elements are being introduced because they have
DOM APIs that exceed that of <object>, and we don't want to overload
the general element with features specific to certain kinds of media.
By analogy, images could have specific APIs too (dontScale/scaleToFit/
These aren't being proposed at present, but overloading object is not
something it seems like we should be telling people to do.
I would expect, if an analysis was done, that the number of people
using <image/> as an empty element (thinking they were using img), and
the number of people using <image></image> as was defined in HTML+ are
both no higher than the background noise of misspelled tags. As such,
I don't believe it would be to any vendor's detriment to change the
meaning of an opening <image> tag to not be empty, since the numbers
of pages rendered incorrectly would stay about the same (just that it
would be a different set of pages). The action, however, would free up
the tag for future use.

In order of importance to me:
1. It's spelt correctly.
2. It's not an empty element.
3. It's spelt correctly.

The point of fallback is ‘help for people who can't see the image’
rather than ‘an explanation of the image suitable for all’. Of course,
if you can provide the latter, that's great, and there's no problem.
Fallback content could be as simple as "Figure 2", where the
surrounding text discusses the image sufficiently that it isn't
necessary to see the image, but users still want to know which image
element on the page that text was referring to (so they can download
it to disk, or whatever).

Aye, but <img> gets me very angry.
I believe this was the worst moment in the history of HTML:
Why did nobody stop this guy at the time? We're still cleaning up his
mess 15 years later :-(
