Impacts of Node Versus Node2D For Root Node?

Question

Are there any? These reddit posts talk about potential issues, but none mentioned seem to exist in Godot 3.1.1:

https://www.reddit.com/r/godot/comments/9xkax8/difference_between_choosing_node_vs_node2d_as/

Even with Node as the root, any Node2D can still be positioned and moved around the viewport. Any Node2D child of a Node that is a child of a Node2D retains its positioning relative to the grandparent Node2D.

The response from MysteryGM in this reddit post suggests that a reason to have a Node2D root is in case you want to position the whole scene inside another scene at a position other than origin of that other scene. Is that a valid consideration?

Doesn't matter. Just use any. You can quickly switch root node type when you need to position things or run into any kind of problems.

Yes, Nodes would be better for maps whereas Node2D/Spatial can be used for features within the game but usually things like players and enemies are RigidBody or KinematicBody.
