mail@gmail.com & mail+label@gmail.com, I did that before in my manual setup so that people can easily switch between OAuth providers, their email address and don't have to remember if they used a + address or not and also that using a + address and then an OAuth provider would just work. Now I'm curious what people actually expect. I know that it got me a couple of times creating unwanted accounts instead of logging into an existing.email_raw column to my profile table and auto populate it from generateLink data so I'll then be able to query profiles to see if there's already an associated profile with an email.
