Why is `ViewModelProvider.Factory` not a `fun interface`? This would allow you to pass a lambda instead.

it's a Java interface so SAM conversion should be applicable

In the latest version, it is written in Kotlin

hmm, found the source synced to <https://github.com/androidx/androidx/blob/androidx-main/lifecycle/lifecycle-viewmodel/src/main/java/androidx/lifecycle/ViewModelProvider.kt>

well, that's probably worth filing a feature request about then

Hm, simply adding `fun` is not possible, because  `Factory` has no generics, and in an `fun interface`, the single abstract method cannot have generics alone. Alternative would be adding generics everywhere or wildcards...
