MarsSeed [1] filed a deletion request for butterfly [2]: Orphan, last updated 2.5 years ago, despite my packaging related change request a year ago.
Last release was in 2018. It seems no one is interested in either maintaining or just using it. Therefore I recommend deletion. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/butterfly/
