How do you know if the old code does not use the optional argument? It could be
any Scheme expression, or even a #{ … #} expression. Scheme has more syntax
than one might think: there could be ; or #! or #| comments and all sorts of
things.
One could special-case (markup->string <symbol>), catching a subset of those
cases. I’m not bothered by the current replacement, but would that make you
happier? In any case, we can’t reliably detect all cases of markup->string
applies to one argument only.
