I'm currently thinking about attempting these kind of things (testing building derivations under different conditions) through the agent tags in the Guix Build Coordinator. I haven't used this functionality yet, but it's mostly implemented. The idea is that agents have tags, that describe various attributes that are important (time=normal, time=future, maybe for example), and builds can also be targeted at specific agents by tagging the builds with those same tags. Where I'm going with this is that I'm not sure a separate build farm is needed, it would be good to just incorperate this in to the build farm used for testing patches and non-master branches.
