Hmm.
The reason footnotes are not allowed in #+title and other keywords is
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=7ebe87e2d5fb6c

    Inserting footnote references in parsed keywords (e.g., TITLE or
    CAPTION) can lead to subtle bugs.  Indeed, it is impossible to know in
    time if that particular footnote is going to be used in the output,
    and, therefore, if it should count, e.g., in
    `org-export-get-footnote-number'.

However, I am not sure about that line of reasoning - we generally don't
know if *any* given footnote reference is going to be used in the output
or not because export backend may skip references or whole parts of the
original Org file. Same for user filters.

So, I am leaning towards reverting that commit - that will allow things
like

#+TITLE: This is a test title[fn::This is test]

If we need special handling for footnotes in title (like using \thanks
instead of \footnote), it is easy.

No idea about how to do it in ODT. If someone familiar with OpenDocument
spec can help, it would be welcome.
