Oops.  Indeed, your view is right.

Still, when would your diff break someone else’s code?

They would need to currently use `local-file' or `current-source-directory'
to reference a file in .config/guix/current/share/guile/site/3.0,
which your diff would break.  But this still seems unlikely to me.

What `local-file' needs is a kind of current-source-directory.
Current `current-source-directory' does a bad job in channels.  Your
diff does fix this.  The compatibility burden is on the channel
authors.  `current-source-directory' would no longer be bad in what we
deem realistic use.
