What is use_crossbow_as_firearm used for?

[DoDoCat]

Seems like not very useful

 

[Pitch]

Whether crossbows will fire with smoke and a sound of explosion or with normal xbow sound.

If I recall it correctly, WFaS is using it, replacing the crossbows with firearms. This way you do not need to activate the firearm-slot if you don't need crossbows anyway.

Afaik it makes firearms use wpt_crossbow weapon proficiency instead of wpt_firearm.
