Do you mean to put something like

  guix() {
    command "$1" "$@"
    hash "$1"
  }

in the default /etc/profile (or wherever such things belong)?

I think this is far too intrusive and magical to do by default, 
considering its limited one-time-only usefulness.  The same goes 
for patching shells.

Kind regards,
