BUR #18339 has been approved by @nonamethanks.
The wiki for flame states it's for "single, clearly-defined source(s) of fire", but this applies to most fire posts that aren't fiery_background. It might have had some use to filter out smaller fires like those from candles, but the examples given in flame's wiki include flamethrowers - this combined with its low post count make it completely useless in that regard. As it stands, flame isn't really anything more than tag padding.
