Wouldn't it be relatively simple to have the ship be automatically stopped as soon as it gets at a certain distance from a land-able object and open some dialog asking whether you want to land / enter atmosphere or something like that to initiate a cutscene / loadscreen?
And if you say no, the ship's computer could make up some in-game excuse, such as needing to avoid the gravity well of the planet, for it to automatically turn around and move away from it.
I mean, I get that they probably didn't expect someone to spend the time to actually go and attempt physically reaching the planet, but after all the attention this thing is getting it could be an appropriate approach to take for when they do the full release, if only to shut people's mouths. It's just one small detail.
