All browsers support at least DTLS 1.2. Does that mean we can remove support for DTLS 1.0 from WebRTC's PeerConnection already?

Apparently Google is planing on removing support for 1.0 https://twitter.com/Emad_Omara/status/1092546483222728706

Looking at the Telemetry data it looks like we would kill <=2% of PeerConnection by disabling DTLS 1.0.

Martin do you think that would be reasonable?

2% is pretty high. It's a lot higher than we'd normally make a move like this. If others are moving, then we might consider 1%. If not, then the number is probably below 0.1%.

If you were to announce this for March 2020 (like we are doing for HTTP), maybe we could reduce the rates enough by then.

It would be good to eliminate DTLS 1.0, especially now that the spec no longer requires it.

Looks like Chrome is getting all kind of bug reports for turning off DTLS 1.0 in 74.

With the intent to unship TLS 1.0 and 1.1 in March 2020 https://groups.google.com/forum/#!topic/mozilla.dev.platform/8EFRYDR3N1c
we decided to also turn off DTLS 1.0 for WebRTC at the same time.

In bug 1583317 we added prefs which enable users to test today with DTLS 1.2 only.

DTLS 1.0 is already disabled. Are there any remaining tasks?
