This is a great plugin and I think it should be standard functionality. My only gripe is that it will collide ungracefully with XF2 [8WR] Discord Integration by @Jaxel if both addons are installed, since they both try to implement the "Discord" login method.
Great add-on and so glad it is free. ThemeHous provides some great services and I'm glad they continue to support this free one. Overall a really good upgrade, especially the connected account providers.
Good addon, it would be great to have the feature of "user self delete" in addition to the deactivation. In the EU it is necessary to fit the regulations of the GDPR, see: https://gdpr-info.eu/art-17-gdpr/
