I looked it up for myself and found that different editors take different positions. To quote from one: "In some scholarly articles, you’ll find hyphenated Latin expressions (such as ex-post-facto research design or status-quo bias). Does that mean those journals’ editors or proofreaders did slapdash work? No. It’s not incorrect to hyphenate Latin phrases, but it’s unnecessary. However, some style guides may recommend hyphenating all Latin phrases used as adjectives (I’m yet to find a major one that does, though)." You've made it clear what the standard is when you're the editor, which is fine with me.
