Which is unlikely, given that it’s redundant with $XML_CATALOG_FILES.

There are changes in the build tools, for instance ‘search-path-as-list’
(used by ‘set-path-environment-variable’, used in gnu-build-system.scm)
expects directories, not files.  And all this calls things

This is a change we could schedule for the next core-updates.
