MarsSeed [1] filed a deletion request for python-pyqt5-pre-release [2]: Not actively maintained. pkgver=5.15.11 is wrong: that stable version has not been released yet. Also the package could have been named better, e.g. 'python-pyqt5-dev' (based on upstream's version suffix for the preview snapshots).
