1] I find it preferable to have footnote text always left-justified to
the beginning of the first character of text, while emacs
auto-fills by default to column 1 and would require unwieldly
toggling set-fill-prefix whenever moving between text body and
footnotes.
Here's what I've done for myself, so far, and if you like it in
principle, you can have it. I'm available to tweak it some per your
suggestions and my ability (eg. modify the footnote functions
themselves instead advising after them).
2] Function `Footnote-add-footnote' in emacs25 defines an optional
`arg', but it is never used.
3] The current default value for variable `footnote-body-tag-spacing'
is 2, which is visually appealing, but doesn't persist upon
`fill-paragraph'. I've tried replacing the space character with a
non-breaking space (integer value 160), which you might want to
consider, but it visually looks like an underscore which is
un-appealing.

This seems to have changed since this bug was filed -- when
auto-filling, things seem to work as expected in the footnotes.
However, `M-q' didn't work in any sensible fashion:
Footnotes:
[1] Foo bar
and then hit `M-q' would result in
Footnotes: [1] Foo bar
so I've added a new fill-paragraph function to the Emacs trunk.

Hmm, you did
(define-minor-mode footnote-mode
...
(setq-local fill-paragraph-function #'footnote--fill-paragraph)
But since footnote-mode is a minor mode, isn't it a mistake to just take
over fill-paragraph-function like that? What if the major mode has
installed some fill-paragraph-function?

Oh, yeah, that's true. How are minor modes supposed to do the paragraph
filling? Hm... For adaptive fill footnote does:
(unless adaptive-fill-function
;; nil and `ignore' have the same semantics for adaptive-fill-function,
;; but only `ignore' behaves correctly with add/remove-function.
(setq adaptive-fill-function #'ignore))
(remove-function (local 'adaptive-fill-function)
#'footnote--adaptive-fill-function)
[...]
(add-function :around (local 'adaptive-fill-function)
#'footnote--adaptive-fill-function)
and I guess it could do the same for fill-paragraph-function? (It
seems like a mouthful, though -- perhaps there should be a helper
function to do all this?)
Hm! Or will using fill-forward-paragraph-function do the right thing
both for adaptive filling and paragraph filling?

I think the footnote--adaptive-fill-function would still be needed,
because fill-forward-paragraph-function can't choose the fill prefix.

Right.
I've looked through the code to see if I could find any other minor
modes that does stuff with these variables, and I couldn't find them.
So I've just refactored out the dance footnote-mode does with
adaptive-fill-function into its own macro and done the same with
fill-paragraph-function.
If this is deemed generally useful, then we can move it somewhere more
central.
