I'd keep it. Some site admins may not feel comfortable with sysops being able to block large portions of internet users, especially if they don't know what they are doing. But, yes, not used much.

This option was making sense when blocking registered users was an experimental feature, but currently it's set to true everywhere and hardly there's any third-party wiki that actually use it. So, does it make sense to remove this option completely?
