What the scene holds
The scene holds its cameras and entities weakly: one its owner lets go of leaves the scene with it, so remove is only needed to take something out while keeping it. Adding what the scene already holds does nothing the second time. Texture cameras draw before screen cameras, and cameras of a kind draw in the order they were added.

Uniforms for everything the scene draws
A value set here reaches every material drawn in this scene whose shader declares the name, so a value that belongs to the whole scene eg the sun, the time, is set once rather than on every material that uses it. A material's own value for the same name wins. The scene's is the general case and the material's the specific one, so a material can override; the scene's values go up first and the material's over them.
