The tag alias #67425 tail_fire -> flaming_tail has been approved.

Reason: Fire and flame are the same thing, yet flaming_tail is way out in front in tag count. Also, fire_tail is already aliased to flaming_tail.

Think you meant it has been aliased.
Also, it is already part of BUR #1144 on topic #30332 (that is still pending approval).

On another note, something of worth noting is @faucet's comment on topic #41139.
Should we have additional subtags for flaming tail tufts?
