They're talking about it and waiting to see if `?` pays off in C# and Kotlin before moving on it.

From C# point of view, I have hardly seen anyone use it outside conference talks about new C# features.

Right now there are 20 years of having null as default and turning it on just generates endless warnings.

So it is left for complete new projects where almost no third party libraries are being used, which right now is very little.

I also hope that C# 10 doesn't get !! for checked parameters, but it might already be too late.

Interesting, got any links?

I do not, but as always this is the Java way. Being the last mover is how Java moves forward with features. They let other languages experiment first so they don't have to support a bad feature for eternity because of Java's backwards compatibility promises.
