It’s a good argument against trying sleeper/generation ships.

In practice, though, the actual sleepers would be so happy to arrive to find a nice McDonalds and a charming small town instead of shuttling down into the middle of uninhabited Arrakis with a 3D printer and a prayer.

Worse: your sleeper ship arrives at what should be a pristine planet. But FTL capable ships beat you there. And they ruined the planet over a few thousand years. And now they’re sending out refugee ships of their own.
