VSE - Turning Clips into Scenes with Compositor

How to turn Blender into After Effects?

Allow the Sequencer to turn Movie Clips into Scenes with Compositor enabled - Composition Scenes!

I have been trying to come up with a good workflow on how to use Blender for Keying and Compositing for Animation but Blender lacks Compositing functionality in VSE.

However, it can have Scenes with Compositor enabled, that can do a lot of the effects. Just a simple Operator that lets us 'nest' Movie Clips in a Scene will bring Blender a bit closer to actual Compositing software.

My proposal:

• When adding Movie Clip into Sequencer, add an Operator that turns the Clip into "Composition Scene"

• Composition Scene is a new Scene with Compositor enabled where the original footage is converted into a Movie Clip Node
• The Operator also opens a new Workspace with the Composition Scene Open and Pinned
• There we can apply compositor nodes

• Going back to Video Editing, we can see that Movie Clip has been replaced by a Scene Clip instead

This could be done by a simple addon, which I might attempt to do :) I wonder if there are any alternative approaches to making Blender VSE more "compositing friendly"?
