I found the following in "The TeX Book", by Donald Knuth:

  The \footnote macro should be used only in paragraphs or hboxes that
  are contributed to TEX’s main vertical list; insertions will be
  lost if they occur inside of boxes that are inside of boxes. Thus,
  for example, you should not try to put a \footnote into a subformula
  of a math formula.

So it will not be easy to make @footnote work inside of @w and it would
be fine for texi2any to issue a warning about this.
