It cannot.

I don't understand where your confidence is coming from, but I'd like to refer you to the proposal:

https://github.com/WICG/email-verification

3.1: The email selection is done through an <input> element. Populating this can be done programmatically.

3.3: The verification consent is out of scope of the proposal, so it can indeed be completely missing.

If you still disagree, then I frankly don't care. The mechanism behind this automatic verification is black-and-white and I've already outlined how it can and most likely will be abused by huge corporations.

Edit: Well would you take a look at that; I'm not the only person seeing this issue: https://github.com/WICG/email-verification/issues/51
