What do you mean by "all issues"? Does it increase the number? Or did you figure out what Chainalysis does to rule them out, and develop a counter measure?
L2 capability is nice. So there's a hash-time lock construct?

FCMP = Full chain membership proofs, that means every tx includes a ring where the "decoys" are all transactions in existence, that bumps the anon set from 1 in 16 senders, to 1 in 100 million, basically removing the concept of decoys and saying your transaction has a sender that is unknown, and can be anyone ever
You should research more about it! I'm not a genius on it but it's the current hot topic in the space, you can watch the dev Luke Parker, or read the paper on it, it also explains a bit more on tx chaining:

Instead of having 15 decoys, as currently, every transaction on-chain becomes your decoy (100,000,000+)
