Description
We don't expose a justification method on the chainHead class and this information might be useful for some developers.
I wondered if we should add this method before stabilizing the chainHead to version 1 to have a more complete API.
From the Substrate perspective, this is quite trivial to implement. I'm not sure what the implementation would look like for the light clients.
Would love to get your thoughts on this 🙏
