Signing in to a Gitlab instance using another Gitlab instance (or Gitlab.com) should import more account settings
This would be a fantastic quality-of-life addition, primarily for self-hosted Gitlab instances allowing signing in with Gitlab.com.
A lot could be automatically imported, such as the whole profile (Twitter, Skype, Linkedin, website url, location, org, bio), localization settings, theme settings, public ssh keys, etc.
Potentially, some of this could be controlled as well using optional oauth scopes which the user could disable during the account creation.
