Look at logic here. The wyvern observer in f2 and fu said that creatures they don't know how to classify get to be elders. Goa is a ???, meaning they don't know what it is. So the obvious conclusion would be that goa is an elder. And if that wasn't enough, it has the same body structure as all of the other "true" elders (4 legs, 2 wings, tail) such as kushala and teo.
