Request #26753 has been rejected by ainola [1]: There appears to still be active development on the repo, and the package is still popular. While protonvpn-cli certainly seems to be the future everyone *should* migrate to, deleting the package seems premature.
exprez135, please do submit a request when you feel that this package is no longer necessary. [1] https://aur.archlinux.org/account/ainola/
