KeepAlive state

[davidknapman-cl]

Is there some way for a component to know if it's a part of a KeepAlive tree? I have a component that only makes sense to use within a kept-alive context but I can't see anything documented that would let me determine that during setup and issue a console warning if we're being misused.

In addition, I seem to keep having to implement:

const active = ref(false);

onActivated(() => active.value = true);
onDeactivated(() => active.value = false);

The Vue Developer Tools seem to have access to this state in some form and show various components as inactive when inspecting the component tree - but is this exposed to components themselves and if so, would it be reactive?
