At a glance, this looks good to me, but testing it is slightly annoying so I haven't done that yet.

To test check the settings.json ex .config/discordcanary/settings.json before and after running NIXPKGS_ALLOW_UNFREE=1 nix run --impure "github:Artturin/nixpkgs/discord-disable-breaking-updates#discord-canary.disableBreakingUpdates"

I was more so referring to testing that older host versions then run properly, however yeah that should be good enough.
