This is something that will most definitely still be needed even after SC reaches 1.0 as you'll never be able to fully guarantee that no one will be able to glitch out of bounds. It's better to implement it sooner rather than later so that we can at least somewhat alleviate all the headaches people have to go through to play this game. The /stuck command should: Check if you're currently under the surface of a moon/planet (and not in a cave). If so, teleport you to the surface directly above you. EDIT: please remember to nullify the player's velocity as well so we don't immediately pancake. Otherwise, it should force you to wait for X seconds with no input (to prevent using the command as an exploit) and then teleport you to the nearest valid location. I'm sure you could make clever use of things like path finding tools, object bounds, and the history of the player's previous positions to find out where such a location might be. As a bonus, CIG would be able to collect metrics on where everyone was when they used the /stuck command and then be able to easily identify problematic locations that need to be fixed.
