If you are running an immutable system like Bazzite it is significantly harder to get yourself into an unbootable state by accident, since if your system-wide change does actually break the machine, you can just boot into an older one. NixOS is quite a bit different, but likewise it is really hard to make the system unbootable just by making changes, since I can just boot into an old generation. I haven't used rescue media for my own machines in probably 5 or 6 years now.
