Why is `Test(Coroutine)Scope` suddenly `sealed`?
That’s breaking my entire test suite :open_mouth:

Comment in code reads
&gt; Since 1.6.0, ERROR in 1.7.0 and removed as experimental in 1.8.0
It’s already an error in 1.6!

I use sub-interface and delegation to add additional functionality.
Alternatively the extension functions should be moved to a new parent interface of `TestScope` that’s not sealed and can be implemented by other interfaces.
