This seems solvable in the xslt/CSS.  Instead of traditional superscript
print the link at normal-ish size with normal underline indicator for it
being a link.  On the website we could possibly even code in a tooltip on
hover to show the note content without clicking or scrolling the page.  And
in this case choosing not to follow the footnote only means one loses out
on understanding why we didn't implement any/some aggregates, not that main
info, which is repeated for each, that they are not implemented.  I'd call
that a top-tier example of when to use a footnote.  And agree we can do
better styling it.
