Add player in faction placeholder for PlaceholderAPI?

[catches]

Just checks if a player is in a faction or not.

To confirm, do you mean a placeholder that returns something like true or false based on being in a faction?

There already are a few placeholders that do things distinct for not being in a faction, such as (I'm not including the %factions_...% bit):

player_role - It's empty if not in a faction
player_role_name - It's the lang.yml PLACEHOLDER->ROLE->NAME entry if not in a faction
player_factionless - It's empty if in a faction, and whatever your lang.yml calls factionless players if not in one
faction_only_space - It's literally a single space if in a faction and empty if not.

Yo @mbax sorry I didn't get to this, but it was more so a placeholder that returns true or false yeah, since I'm using plugins that have conditions where I'm trying to detect if a player is in a faction, and I don't know how to do that with just empty spaces.

Do those plugins truly only take 'true' or 'false'? That's very odd to use placeholders that way and not allow for detecting if(value is empty) or similar for using that empty/notempty string.
