It's been all but deprecated in TLS 1.3... however, it's been replaced with ECDH/ECDSA - which the NSA is now recommending against: https://threatpost.com/nsas-divorce-from-ecc-causing-crypto-...

That's mostly bullshit. NSA is just saying "don't start a multi-year project to upgrade from RSA to NIST P-256 because you will not be finished with that upgrade before we'll ask you to upgrade to a recommended PQ crypto scheme".

There is nothing wrong with X25519 and Ed25519, except that they are vulnerable to quantum computers (like anything else currently in use).
