MarsSeed [1] filed a deletion request for qtchooser [2]: This cannot be installed on Arch Linux since 2018, because qt5 conflicts with it, but this package actually would need both qt4 and qt5 to function. Notified the maintainers of AUR dependents imageplay-git and qfsm in Jan 2024. (Though both seem to be abandoned, defunct packages from 6+ years ago.) Safe to delete this obsolete, useless package. Any package that would actually need this could in fact configure its build to find the correct qt dependency (qt4 or qt5) directly, so there is no benefit in keeping this, only detriment.
