I think we forgot, indeed. One thing I don=E2=80=99t quite like about the patch is the fact that =E2= =80=98guix substitutes=E2=80=99 connects to the daemon in =E2=80=98content-addressed-i= tem?=E2=80=99. Also, one could argue that we=E2=80=99d steer users towards downloading fro= m our server, which could be a privacy concern (probably not a strong argument since one can easily change the substitute URLs.) Thoughts? Ludo=E2=80=99.
