This can be pretty annoying for users and developers though. If the user forgets what account they last used and selects a different one next time then it ends up creating an entirely new account unassociated with the first. If I ever do social integration, I require a plain old email based login first and then allow them to connect their social accounts to it.

One way around this (from the developer's side) is to federate together different identities for a user using something like dex [1], and segregating your login and signup paths, so attempts to login will never create a separate account.
