MarsSeed [1] filed a deletion request for python2-sip [2]: This Python2 based sip 4 tool is no longer needed by any functioning package. The only remaining AUR dependent is qgis-crayfish-plugin from 2018; it is broken. But its latest upstream version works with Python3. I've notified its maintainer and flagged it OOD. Safe to delete this now. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-sip/
