MarsSeed [1] filed a deletion request for vkroots [2]: Upstream does not have release tags. The code is maintained sporadically (just a few times a year).
It's enough to keep AUR/vkroots-git [a], which is always up-to-date (as opposed to this package, which as of now is not). [a]: https://aur.archlinux.org/pkgbase/vkroots-git [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/vkroots/
