I think you mean “degraded”, but there’s no such mode, where did you
read about it? :-)
The last paragraph at
<http://www.gnu.org/software/guix/manual/html_node/Build-Environment-Setup.html>
mentions use of the daemon by non-root users, and suggests that this is
the last resort.

My guess is that it’s not widely used.

Yes, that’s an issue. Unfortunately, users would sacrifice
reproducibility by running the daemon as non-root (and we would get
reports about builds that fail unexpectedly), and using a non-standard
store directory may also hit shebang length limits and so on.
So I think we must bribe a bunch of HPC sysadmins ;-), get experience
with real system-wide installations on such systems, and see what needs
to be adjusted. Thanks to Ricardo and his lab we already have some
feedback: <http://elephly.net/posts/2015-04-17-gnu-guix.html>.
If you are in a position where you can experiment with such a setup,
your experience would be invaluable!
