This is pretty far from what would be needed to say 'Email registration is dead'. Users may be annoyed by it and it may help in niche cases to exclude email requirements, but for most webapps this will not be possible as users will not even be able to reset their password then.

Totally agree. This will depend by business. We're were just pointing out that it makes sense to challenge the norm, because people are so reluctant to give their email addresses.
