Why? It's needed, I believe the majority of the forum users support this.
The last classifieds update was a pretty extensive one, and a lot of what it did was condense the number of subforums, i.e., revolvers rolled back up under handguns as a subcategory. I don't see a likely scenario where we reverse that and go back the opposite direction. Even less likely is a scenario where we go even further and segment into specific platforms. It's not happening.
It's certainly not "needed", and "majority" is a bit of a stretch as well.
