Is there any reason why the owner is automatically overridden when child node is moved in the tree?

I use scenes as collections of related logic. After instantiation, I remove the children from the root node and add them to layers. This is necessary because some layers are viewports/canvasgroups.

However, when I do so, the owner is automatically overridden. I honestly fail to see why this is happening. I think I would much prefer if the PackedScene.pack() handled that on it's own, just packing the nodes that have the root node as an ancestor instead of add_child() invalidating this relationship.

Currently, I have to create pseudo owner with metadata.

Wouldn't it be much better if pack() was to recursively pack each descendant of the root node?
