I agree.  There is no advantage to sharing the store that I can 
imagine is worth the risk and burden of compiling your entire Guix 
or Nix world from scratch because you can't use substitutes.

Unless somebody objects, I'd like to (wait for it) nix this from 
the manual entirely.

It may or may not be true still, and even if it is, it's nothing 
more than a random Fun Fact that doesn't warrant encouragement in 
official documentation.
