I would guess it has been influenced by the localedir notably used by
GNU gettext (/usr/share/locale). Or maybe mandir (/usr/share/man),
which also supports localizations according to FHS:

Note that filesystem hierarchy standard already turns the system into a
big soup. If you want nicer structure look at GoboLinux or Nix.
