[aur-general] AUR4 keywords in PKGBUILD?

Is it possible currently to set the keywords/tags in the PKGBUILD itself instead of on the website? (Previously, we had to set categories on the AUR website, but that felt suboptimal.) e.g. a keywords=('cats' 'dogs' ...); variable? Or, alternatively, would people be amenable to adding an ssh command in the AUR git-shell to add/remove/set keywords?
