That’s because glasses basically bypass the eyes/attention detection feature. If you don’t have that feature enabled you don’t need the glasses. That said it would be quite obvious that this attack vector would work, I don’t think that people just realized what happens when you put on glasses and train FaceID to unlock with them. It took like 10+ pin unlocks until FaceID comfortably recognized both my sun and reading glasses since I don’t wear either that much. If I never wore them it would likely mean that this would never work at all since there was no pin confirmed unlock which updates the model with glasses on.
