This mechanism is incompatible with deploying draft versions of TLS 1.3. Suppose a draft M client talks to a draft N server, M != N. (Either M or N could also be the final standard revision should there be lingering draft clients or servers.) The server will notice the mismatch and pretend ClientHello.version is TLS 1.2, not TLS 1.3. But this will trigger anti-downgrade signal and cause an interop failure! And if it doesn't trigger, all the clever tricks around ServerHello.random being signed in TLS 1.2 are moot. We'll put this back when the dust has settled.

BoringSSL
BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
