Exactly as the title says. Vanilla weapons don't have any visible weapon properties and there's no way to enable them. This is immersion-breaking without addons and causes issues with addons such as Scape and Spartan for 1.12.2. Is there a way to change this in the config, or has this not been added yet?

Stale issue message

Stale bots suck. They only serve to artificially increase repo activity.

I don't understand how vanilla weapons not having weapon properties/traits can be considered "immersion breaking". The weapon property/trait system is designed for my mods weapons only and doesn't affect how other mods weapons work.
Also, how does this cause issues with Scape and Spartan? I need details for this in case something can be done to fix this. Without it, there is nothing I can do.
