Can you attach the links to the newly added checkpoints?

And there is no meaningful way to review the filtermap checkpoints right?

There is no quick and easy way right now. I want to add some extra checks to reverse indexing that would detect if the checkpoints are wrong but I did not get around to it yet. Right now the only way to check is to remove the hardcoded checkpoints from the source, reindex the entire chain from genesis, export the checkpoints from your client and compare the json files. I did that yesterday for all of the three networks and they exactly matched the checkpoints from the previous indexing.
