> You could get a false positive from a pre-biotic but molecularly complex planet, such as Earth in the 100 million years before the origin of the first self-replicating genetic-information-containing entity.

That would still be incredibly useful. 100 million years is only 2% of the Earth's age, for comparison, so it's very unlikely that any given planet would be in this state. Even if it were, it's hard to imagine biologists would balk at a chance to study a bona fide pre-biotic environment.
