Why is distro detection desirable?  I often found myself trying to 
work around buggy distro detection.

(BTW: it’s called “Guix System”, not “GuixSD”.)

It is also not necessary to have /etc/config.scm.  I, for example, 
have all my system configurations in a different directory.

Guix is often used on top of other distros, so the presence of 
/gnu/store is not enough to be sure that the distro is Guix 
System.
