MarsSeed [1] filed a deletion request for gnome-shell-perf [2]: Unmaintained fork of gnome-shell from Dec 2021 to Jan 2022, short time effort, abandoned. VCS package in disguise.
This is not the same as AUR/gnome-shell-performance, which is up-to- date. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gnome-shell-perf/
