A hand-waving mention of "revealing the attribute to the UA" and "user
preferences, options etc." is exactly what I want to avoid. I would
prefer we say something informative and non-normative such as:

Long image descriptions should be made available to the user through a
visual indicator. This can e.g. be through a link in the image's
context menu which can appear on a right-click on the image or after
pressing the image with your finger for an extended time. It could
also be through an icon somewhere on the image, or listed "on the back
of the image" e.g. if the UI allowed to "turn it around", or any other
means that the UA deems appropriate.

Would browser vendors resist such a paragraph and the implied
implementation consequences?

I think it would need to be for all three. Those that can see should
get the visual encumbrance, while at the same time it should be
exposed to AT through a11y APIs.
