"Explosive Concoction" not having the "Detonator" tag - intentional?

The fact that a Pathfinder can easily explode a Gas Arrow poison cloud by using Flame Wall's guaranteed ignite (a spell!), but not by using its own ascendancy skill, Explosive Concoction, is just odd.
Is this intentional? Because it seems so intuitive for an Explosive Concoction to be able to detonate a poison cloud. Yet, it doesn't.
Feels unintentional.
Either way, I'd like to suggest adding the "Detonator" tag to the skill.

Don't know if you can bump in here, I think it's my first time posting. Agree on Explosive Conc needing the Detonator tag and ability. Just visually speaking you throw the thing it explodes and leaves flames on the ground. Tried to use Econc with the Decompose gas cloud from the Unique boots and you cannot detonate the cloud.
