TLS implements PFS (perfect forward secrecy) by generating an ephemeral asymmetric key pair for the session, usually through DH. In other words, breaking the session key pair will only reveal the plaintext of the current session for the current client. No previous communication is broken, so the NSA would have to traverse the history for each client.

And for a target of interest, given quantum computing, it would not really provide any real protections. I could see how recalculating the key would be well worth it, if you really want the data.

Agreed, it won't help much in that case.

This case is a targeted breach of confidentiality not unlike a phone wire tap, still not allowing bulk surveillance. Not bad altogether.
