Do you know if there are other use cases than Emacs for this? I vaguely remember that =E2=80=98EMACSLOADPATH=E2=80=99 unusual handling of= the empty entry is why we didn=E2=80=99t have it in =E2=80=98native-search-paths=E2= =80=99 initially, and why Alex Kost had come up with a different mechanism instead.
