Jetpack Compose version: 1.7.0 SNAPSHOT

Jetpack Compose component used: Animation

SharedTransitionScope is currently a class, but it's used as a receiver for shared element modifiers. I'm trying to create my own scope type for navigation within my app, exposing things such as:

AnimatedVisibilityScope
SharedTransitionScope
Whether or not the screen is at the top of the nav stack

I'd like to make my scope type implement SharedTransitionScope, but since that's a class rather than an interface, I cannot. It'd be nice if that were an interface.
