keyrings on the AUR

Hi, I'd like to ask what's the current status on gpg keys, "keyrings" on the AUR? A few years back they where removed[1]. If I search for 'keyring' right now a few pop up. I guess there are different reasons for them to appear, like for example the 'linuxmint-keyring' is different from the 'alph-keyring', where one is from a pacman repo and the other one is not. However it would be good to have a consistent rule/guideline what's OK and what not.
