I used to follow the latest stable channel. After embracing flakes (which made version pinning easy and integrated), I’ve moved to just pinning unstable for the fresh packages. I update the flake about once a month, when I have spare time to deal with potential breakages in case there’s any.
Interesting. How often does it trigger mass re-download from the binary cache? I’m on a not-so-fast home internet connection, so if mass rebuilds occur too often, I would spend a lot of time waiting for the downloads.
