I'm quite confident, adding /usr/share etc. here as default would be
wrong from a guix point of view: This would break isolation of
environments. On a foreign distribution this would even give the foreign
distribution's installation precedence over guix's.

Anyway: Let me ask my question differently: Should the user be able to
*overrule* or only to *extend* guix's installation?
