—This is not a bug report, just a suggestion/feedback—

Since the majority of supported apple devices have the Face ID feature, which uses the TrueDepth Camera System, we should utilize this ability to get accurate facial data when using face tracking that’s soon to be implemented.

For those that don’t have the TrueDepth System, should use the camera by default. But if the TrueDepth Camera is broken or not working as expected (like broken face id) you should have an option to disable it and use the camera instead.
