Is TSA gradually installing the facial recognition at every domestic airport? Do I expect almost every major airport to have this by next year?

As per title. What happens if someone has underwent surgery on their face and needed to fly on the very same day? I dont think the facial recognition will work. I heard someone saying that in the future, they might not make it optional. Also, for foreign nationals (with foreign passport) flying domestic flights, would they be looked at more suspiciously if they decline facial recognition?

airport expect facial facial recognition major next privacy recognition tsa work
