yeah, kinda true -- though there's a great deal of extra uncertainty about M-dwarfs in particular in comparison to more sun-like stars, just because we did have this one example to study of that.
But on the other hand, we see all kinds of planet types around all kinds of different stars that pose similar problems (say superearth habitability), so even that only applies to questions about planets more similar so some of the types we can find in our own solar system.
