"Lock to Object Mode" Outliner Toggle and/or "Lock Vertices" Vertex Group option

It would be good to have an additional toggle to prevent accidentally editing objects in any non-Object Mode (Edit, Weight Paint, etc). The Selectability toggle is a bit too restrictive in my opinion. Here is a mockup - icon to be discussed, as it could be confused with the "Lock" icon in the Transform panel.

---

Unlocked mode

Object can be edited in any compatible modes

---

Locked mode

Object can't be edited in another compatible modes, but is still selectable/transformable.

---

Other option

Maybe we could have a toggle in the 3D Viewport too?

---

Note

There's also this option in the Edit Menu which isnt exactly the same.

Other idea: Lock Vertices with Vertex group

The idea is to use the Vertex Group to "lock" vertices to prevent any undesired transform operations.
