Ha. You want STABLE, use NixOS.
If you’re cannot parse the configuration file, you don’t update. It is perfectly, 100% stable, about 60% of the time (when I change my config file without an error).
nixOS appeals to niche audiences who like to brag about it. I think it is not a good idea to base everything on config files, since there is a lot of room for user error
The config files literally won’t compile if there is an incompatibility or error in the code.
Also, every distro has an audience who love to brag about it. The worst part of being a Nix user is I can no longer say “Arch BTW”.
You’ve literally described Linux. Wasn’t even a week ago we had a circle jerk on here about how great it is that everything on Linux is an ascii file (technically inaccurate on most distros) rather than a nasty nasty database where the most you can fuck up at a time is a single entry vs breaking the schema of an entire file.
