The requirement to list an accommodation is the scariest one, because employers have the right to fire you if your religious beliefs cannot be reasonably accommodated.

And it's the most subjective. Even if you believe what the CDC says about the vaccine fully, the risk posed by a single unvaccinated individual in a room full of vaccinated individuals is insignificant. Certainly less significant than other risks a person is expected to accept by existing. So a reasonable accommodation should not be needed.

This is the type of thing that is argued and often won in decent courts. But someone needs to sue and set precedent.
