That's not what's at problem here. It's like how you can't swap parts of the logic board in case they fail (even if they rarely do) because of the design - I don't think many people will be mad at Apple for that. This is where two screens from brand new iPhone 13's can't be swapped without Face ID (which is no longer even attached to the screen) no longer working. Now, this might not be deliberate, especially given the setting app's screen warning doesn't say anything about Face ID being disabled, but it's not a good sign.
