Could we inject labels in all footnotes? If so we could simply use
\textsuperscript{\ref{FN-LABEL}}
In place of
\footnotemark[FN-GUESS]{}
It seems \footref of scrextend.sty has some extra robustness built into it
but until someone complains I think the \textsuperscript hack should be
enough and better then what we’ve got.
Example:
\documentclass[11pt]{article}
\usepackage[hidelinks]{hyperref}
\usepackage{parskip} % to avoid \noindent
\usepackage{scrextend} % to get \footref
\begin{document}
\addtocounter{footnote}{1}
Text\footnote{\label{org925ce52} Footnote.}\\
Text\footref{org925ce52}\\
Text\textsuperscript{\ref{org925ce52}}\\
Text\footnotemark[2]{}\\
\end{document}

Cool! I hadn’t noticed that these are part of info.

It should be enough to allow Jorge to write a simple filter to address
original issue.
