Way-Shell – A Gnome-like shell for Wayland compositors
github.comIsn't this quite exactly like Regolith? They started supporting Sway / Wayland now and integrate Gnome stuff.
Since you say 'quite exactly', definitely no.
Is it another desktop shell? yes lol.
It mirrors the look and feel of Gnome and will stay Gnome adjacent as they introduce new UI changes and feel.
