My questions are, how does the glibc team choose the minimum kernel
version? What could go wrong if we apply this patch and somebody uses
Guix on a pre-3.2.0 kernel?

Perhaps they simply chose to not support glibc on any kernel that is not
supported upstream; 3.2.x is the oldest supported release series. But,
we should have some idea of their reasoning, in my opinion.
