MarsSeed [1] filed an orphan request for archlinux-themes-sddm [2]: Unmaintained since 2016. Commenters have requested many required PKGBUILD adjustments since 2017. The most important is the addition of depends=qt5-declarative, to ensure it works with thr current sddm (which, by default, only requires qt6 deps).
