MarsSeed [1] filed a deletion request for python2-dbusmock [2]: Orphaned, last updated in 2019. This was only a testing/mocking library for use during the build/check of some Gnome components.
As this legacy Py2 package has no dependents on AUR and is not essential, I am suggesting deletion. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-dbusmock/
