MarsSeed [1] filed a deletion request for compiz-boxmenu [2]: Discontinued since 2015. Package is abandoned, and depends on a broken, EOL package 'python2-lxml', which has been failing check() for 1+ year now.
Seems not useful to keep. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/compiz-boxmenu/
