Browser vendors announced they’re phasing out obsolete versions of TLS in March 2020.

In an early-2019 release we should flip MODERN_TLS to support this 2020 spec, and change COMPATIBLE_TLS to cover everything that was dropped.

Why milestone 3.12 based on above comments?

Using “next release” as a mechanism for “short list of things to consider for next release”, with the expectation that it’ll slip one or two. Gotta cut a release soon too.

... I created a new milestone “Backlog” for issues that we’ve triaged.

This step is done. Next step comes in 2020 with #4499!
