I use btrfs for several years now — not with Guix System, though I do have 
Guix installed on top of Ubuntu on btrfs so I do have /gnu/store on btrfs. 
My experience is that it is zero-maintenance, at least on a personal laptop 
workload.

Btrfs has matured a lot over the years, so there’s a fair amount of 
outdated advice still floating around on the Internet. You’re probably 
thinking of the ‘btrfs balance’ command. In the past, it was useful to run 
it every once in a while to avoid spurious ENOSPC errors. This problem has 
since been fixed, and current advice is that regular use of “btrfs balance” 
is now considered detrimental rather than beneficial since it puts more 
load/stress on the disk without any practical benefit.
