Downside of (guix build utils): it makes it harder to modify switch-
symlinks.  I don't know if that's too much of a downside in practice. 
Also, there is a bug in switch-symlinks:

(use-modules (guix utils))
;; simulate an interrupted switch-symlinks (C-c, power interruption, ...)
(symlink "target" "link.new")
;; now try again
(switch-symlinks "link" "target")

ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure symlink: Bestand bestaat al: "link.new"

If we move it to (guix build utils), I'd prefer the bug to be addressed first.

Greetings,
Maxime.
