Request #28897 has been rejected by ainola [1]: Confusingly, -bin suffixes are not required when the product is proprietary (i.e. there is no possibility of having a build-from- source package). It's a backwards thing, I know, but it is how it is. So I'll be submitting a merge request the other way around.
Glad to see you got co-maintainership status! [1] https://aur.archlinux.org/account/ainola/
