Barring some startling new cryptographic attack, deprecation of TLS 1.2 is
looking to be at least 5 years in the future.  TLS 1.3 gets you a
streamlined handshake for faster TTFB, and the crypto is better analyzed,
but the adoption of 1.3 is being driven by this sort of features and not by
flaws in 1.2.
