Hi there, is there a reason not to have a type parameter for the delegate on a `KProperty`?
if there was, one could write extension functions, depending on the delegate type. I.e.
```
fun KProperty&lt;*, BehaviorRelayDelegate&gt;.subscribe(O: Observer)
```
and use it like
```
val v : Int by BehaviorRelayDelegate(0)
::v.subscribe { Log("Value changed to $it" }
v = 2
val v1 = v
```

Property delegation is considered an implementation detail of a property, thus a statically reflected `KProperty` cannot expose that detail, i.e. the delegate type.
