Some significant development needed before this can be done ethically (asking everyone you are talking to to consent to having their names and faces matched at your service provider cloud is likely more awkward than asking what their name was again).

In theory that feature is possible to do in a privacy-respecting manner but that will certainly not be introduced by Meta.

Seems like if they are one of my linked-in contacts or Facebook friend and they have their face publicly available on their profile, then it would be fair game.
