Yeah, I can get you not wanting player actions affecting the world in D&D. Let me ask a question about this example...
Is there anything that would make something like this more palatable to you? Or is it wholy anthemic to your sense of gaming when playing D&D?
Frankly, I have fewer quibbles with mythic than player affecting world.
My concern for the Rogue Get In Anywhere power is unintended consequence/complete removal of obstacle type. It's nature is similar to a more focused version of Dimension Door/Teleport which have too few counters in the game as-is.
As a player, I am much less comfortable with the Just the Tool for the Job ability and other such things that force the player to engage in world-building.
