    "name": "viorela.ioia@softvision.ro",
    "user_id": "github|35528677"

I only see this user, which means that the switch worked (github only sends the primary email to us) and that this user id was phoenix1moz's user id.

I don't know how the code handles this in Mozillans, but from a rule/auth0 point of view it would send the same data yesterday and today
