I had talked to Heavy about it, and it sounded like that being Green wasn't enough to be a POI these days. I'll write up a submission though! (Gotta think of a name for it first)
So we're close to almost 30 "green" gas giants by my last count. That's high enough count / low enough rarity that only the spectatular ones are going to be future-POI worthy, and we may demote older ones that are not very green to the Archived section.
