MarsSeed [1] filed a deletion request for plasma5-theme-lavender-git [2]: KDE5 package, not compatible with current Arch Linux / KDE6.
Upstream seems to be working on a KDE6 port, albeit at a slow pace.
Once there is a viable KDE6 version, new plasma6-themes-
lavender{,-git} package(s) can be submitted for that.
