Component used:Androidx
Version used:Androidx.AppCompat 1.6.1
Devices/Android versions reproduced on: All

I would like to use https://developer.android.com/reference/android/app/AppComponentFactory that is defined in Api 28 in my project to enable constructor injection in Android Components. (yes, we are currently using Dagger.Android and have considered migrating to Hilt, the build time cost this adds is high for our project structure and we are exploring other options).

However, Androidx registers CoreComponentFactory when included in the project. I would have to use tools:replace and opt for my version of CustomAppComponentFactory which probably would result in missing features and crashes if I read the code right.

I could update my Custom AppComponentFactory delegate to CoreComponentFactory, However, this class is marked Restricted to LibraryGroupPrefix https://android.googlesource.com/platform/frameworks/support/+/refs/heads/androidx-main/core/core/src/main/java/androidx/core/app/CoreComponentFactory.java.

Could CoreComponentFactory be used as delegate. i.e. the restriction removed please.

Or Could framework be updated to enable multiple AppComponentFactory using delegates. Without these updates AppComponentFactory is literally only usable by Androidx libraries.

If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue.
- A screenrecord or screenshots showing the issue (if UI related).
