While maintainer has modified the package, the deletion request stands. As stated earlier, upstream is unmaintained, and the binaries are not useful in current state on vanilla Arch. Installing the following packages make no difference: extra/noto-fonts-emoji, aur/noto-color-emoji-fontconfig, and aur/ttf-twemoji.
