Ive noticed its has been any activity in their github for a longtime. https://github.com/dylanaraps/neofetch
There are a few more info that could be added nowadays like Display Protocol (Wayland/X11) and Display size. FastFetch does this but Neofetch is globally recognized.
Fastfetch vs Neofetch
it could display more info, but it doesn’t need to. And as far as projects go, if you don’t want a full diag, or have an ARM cpu (as someone else said), I’d argue it’s done. You don’t need to change a finished program.
