I completely agree. I think it would be a great improvement, since, as
Colin Baxter says, in academic articles it is a very common practice to
add foot notes to the title of the article or the name of the author.

As for the \thanks{} command, org exports the keyword #+email within a
\thanks{} command as '\author{Name\thanks{email}}0. I don't think two
\thanks macros collide within author (assuming the user adds the email
and puts a footnote in #+author. Anyway, I think the most common thing
is to put the email below the author's name, not as a footnote, but that
is another topic and also depends on the style of each publication,
journal, etc.

I don't have much idea about odt, but I think the problem comes from a
type of nesting that is not allowed in the odt xml. I think org exports
#+author inside the initial-creator tag:

(format "<meta:initial-creator>%s</meta:initial-creator>\n" author)

And within that tag the code for a footnote produces an error when
opening the document. If the footnote is placed right after
</meta:initial-creator>, there would be no problem.
