Given that teachers are no longer competing for student attention in class, that is one single and quite important positive which doesn't require an academic study and referencing to demonstrate.

I'm not sure what you were hoping to achieve with the request for evidence, but what you're asking is not yet subject to a longitudinal study. The move has certainly been praised by educators, and that should be enough given it's the first or second year year of implementation in many cases, and what they are advocating for isn't a social taboo, nor draconian.
