Teleporting from other dimensions with early-game stuff should be in line with Waystones.
I would disable for once and let Waystones manage that.
Don't know if this would disable teleporting with enchanted keys, but if it does, would only add an extra step of going to that dimension and using the key (no problem with nether as you just need to enter the portal, but for space travel if you lose a rocket you are in trouble, people need to make a good use of items like Enchanted Bundle that you can put in a item to save on death).
