Jolt is purely a 3D physics engine. There are other extensions out there that aim to implement the 2D physics API in Godot, like the Box2D extension for example.

Is there any chance we could revisit this decision? The 2D alternatives like Box2D or Rapier2D provide some minor improvements but do not simulate well a chain or a rope and I don't think they ever will. Jolt physics has perfect rope simulation. They also have a much smaller community.
Modifying the GodotJolt to support 2D nodes seems so much easier than modifying the whole game to 3D nodes with fixed z axis (as for example, TileMaps don't exist in 3D, etc.) as a workaround...

No.
and I don't think they ever will
Rapier2D just got a new solver that should help with exactly this. Once the Box2D extension moves over to Box2D 3.0 (aka "Box2C") you should see a massive improvement there as well.
