Should I ever run another DnD campaign I would implement something similar.
I had two possible ideas for altering teleport mechanics:
1. When you teleport you dont automatically appear at your location. You spend a short period of time (3 rounds or so) travelling at great speed through the Astral Plane. When you arrive you do so in a large eruption of magical light and thunder which grows over the course of your travel.
2. You cannot teleport to an area you have not specially prepared with a magical diagram costing 100g or so.
I was less bothered about the effect of Dimension Door than Tekleport. I do struggle to see how any society which has lived with the various uses for magic for any period of time hasnt developed measures to block or expose a variety of efects such as:
Teleportation
Invisibility
Shapechanging
Flight
Major creation
Mind Control
These are probably the major ones which really affect commerce and defence, something any society or kingdom will be interested in.
