This comment looks more useful to me to put in the source code, to help
future readers of the source code, otherwise they would have to dig
through the git history.  As mentioned previously, this could be
something like:

   ;; While according to RFC 7617 Schemes are case-insensitive:
   ;;
   ;; ‘Note that both scheme and parameter names are matched
   ;; case-insensitive’
   ;;
   ;; some software (*) incorrectly assumes title case for scheme
   ;; names, so use the more titlecase.
   ;;
   ;; (*): See, e.g.,
   ;; <https://[bug report 1]/>
   ;; <https://[bug report 2]/>

which would also address the issue of not forgetting that Guile's old
behaviour is correct, it's the other party that's not following the
specification.
