Steps to reproduce

It would be nice if Edge DevTools could log a message for sites that are running on TLS 1.0 or 1.1.

As we get closer to disabling TLS 1.0 and 1.1, we should log a message to the console for sites that do not speak TLS 1.2 (or 1.3), and link to a useful resource, perhaps https://blogs.windows.com/msedgedev/2018/10/15/modernizing-tls-edge-ie11/, and better docs in the future as we have them.

We just landed a similar thing in Firefox Nightly, see https://bugzilla.mozilla.org/show_bug.cgi?id=1512505, the message we ended up with was: “This site uses a deprecated version of TLS that will be disabled in March 2020. Please upgrade to TLS 1.2 or 1.3.”

I filed https://bugs.chromium.org/p/chromium/issues/detail?id=955645 for Chrome – I’m not sure what the release schedule is for Edge on Chromium. If it will be stable by Oct 2019-ish (when browsers will start to disable TLS 1.0/1.1 in pre-release builds (maybe)), this is a WONTFIX. But if it’s later than that, it’s probably good to land this in current EdgeHTML Edge DevTools.

See the attached screenshot for how this looks in Firefox Nightly.
