Given how prevalent the tracking of users is, anonymous or otherwise, I'd be extremely pessimistic about this assumption.

Same here. I don't want the system to even try to recognize me. No one's doing this stuff on site, which means that they'd be uploading my face to a cloud provider and using their system, which means they'd be doing the things people are having a problem with in the first place.
