Exactly! “Tidally locked” means it is a dead planet for all intents and purposes. It is of my opinion that a planet’s rotation is just as important to sustaining life as being in the “Goldilocks” zone. They must be getting short on grant money.
I have trouble with this, too. If a planet is tidally locked, it would get searing hot at the point that has the most direct sun, and freezing cold on the back. Although atmospheric winds would moderate this somewhat, I can’t see a situation where life would take hold without any sort of day-night cycle or where the sun never moves in the sky.
