I don't see how Face ID is inherently an "epic pain"
The fact that the phone only allows one face is a deal-breaker for me. My wife needs access to my phone (and vice versa). I'd prefer we don't have to memorize each others long/complex passcodes. With TouchId, this scenario is handled. With a single FaceId, it's a loss of functionality.

3. One of our phones is unusable (forgot it, battery dead, etc), so need to use the other.
