Sounds interesting, but since I haven't been in touch much with this topic I ask myself: Does this have any benefit for my personal home-computer usage?

For a long time I have the urge to try out Nix, because I clutter up my computer way too fast and therefore often get mad and just install a fresh system. This works fine with my files, but there are always applications which I forget about and forget to save configs. So having this all in a git repo to spin it up fast would be nice. Is bootc, fedora silverblue and so forth trying to achieve something similar?
