I totally agree. No objections. When I brought up this matter, I thought
it might be just a little tweak to the org export code. I didn't realize
that there would be this many complications.

As for my use case, I can handle it easily enough without using
footnotes. So, I don't really need footnote support in image captions. I
only brought it up because I thought it might be a more generally useful
feature than my specific use case. So, this feature, if implemented, can
definitely wait. No hurry.
