--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- I've already reported it as a potential defect in the standard, so it will get addressed (either by fixing the standard or giving justification for leaving it as is). The Filesystem library is not meant to support URIs, so I don't find your argument convincing.
