Imho I don't think Guix needs to do anything to address PEP 668.  PEP
668 concerns traditional distros, in which pip and the distro package
manager may both write to the same location (that location typically
being /usr/lib).  IIUC it does not concern Nix or Guix, whose store
paths should already not be written to by pip.

Regards
