Slippery slope (fallacy)
Not when they say at the same time as announcing this feature, that this is the direction they want the game to go in. An we already seen a lot of moves to making flying and moving around faster, in fact I think in the last 3 updates have all produce ways to travel faster in this game. With hints in galnet articles even faster ways to travel being introduced in the future.
So yes we seem to be on the slippery slope to instant teleportation of players themselves as they "lower barriers to entry".
Not exactly desirable, but not everyone playing ED have strategic mind or play for strategic purposes.
Not every game have to be design to be played by everyone or fit everyone playing style.
