way to see/visualize all chains that include a certain block

[antiochp]

Given a block (hash) it would be useful to be able to view all chains (all heads of chains?) that include this block.
We see a lot of forks in testnet1 - and it would be great if we could know what forked off ahead of a given block.
So a node operator could see what is ahead of them during syncing or if they appear to be on the wrong fork.

@antiochp I've started working on this during testnet1/2 but stopped on later testnets where only a handful of forks happened. Are you still interested in this feature?

It might still be useful - but not sure how useful now.
Feel free to close this.
