I'm less optimistic. Between the fraction of the planet's surface that's suitable for life, the lack of tides, the (likely) lack of plate tectonics, and impairment of the various cycles ( https://en.wikipedia.org/wiki/Biogeochemical_cycle https://en.wikipedia.org/wiki/Biogeochemical_cycle ) - tidal locking to the star will profoundly degrade the planet's suitability for life.
Tidal locking may also rule out having a planetary magnetic field. Though "protect the atmosphere" may not matter much, if said atmosphere (plus the water) has all condensed and frozen on the dark side of the planet.
- mapt 2y agoDepending on the thickness and composition of the atmosphere, convection may be sufficient to prevent ice buildup. The thing about a tidally locked planet, and about marginally habitable planets in general, is that whatever the average, there are a wide range of surface conditions and often the spectrum is large enough that some subset of them are habitable.
