MarsSeed [1] filed a deletion request for metacity2 [2]: Unused, unneeded old gtk2 version of metacity from 11 years ago (2012), whose latest version is carried by extra repo.
Metacity is already part of the GNOME project 'Flashback', providing classic Gtk2-like application look even when using newer toolkits like gtk3. Safe to delete this superfluous PKGBUILD. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/metacity2/
