Trick attack: Opperative weapons only or anything un unweildy?

[BigNorseWolf]

Can you trick attack with any not unwieldy (wieldy?) weapon or just ones that have the operative property?

Operative

An operative can use the trick attack class feature with a weapon that has this special property. Any character can add her Dexterity modifier rather than her Strength modifier on melee attack rolls with weapons with this special property.

Trick attack: You can’t use this ability with a weapon that has the unwieldy special property or that requires a full action to make a single attack.

CRB 93
"As a full action, you can move up to your speed. Whether
or not you moved, you can then make an attack with a melee
weapon with the operative special property or with any small
arm."

The last part in the paragraph is probably to rule out Small Arms that require full action to single attack and/or are unwieldy, such as plasma pistols.

I believe it is also to keep someone from slapping a Blast Weapon Fusion on a Small Arm and then making a Trick Attack that hits everyone in the cone with a boatload of bonus damage.
