/**
 * NOTE(brentvatne):
 * AppLoadingPlaceholder exists to smooth the upgrade experience to SDK 40. The
 * placeholder behaves mostly as expected with the existing API, however it
 * will no longer leverage any native APIs to keep the splash screen visible.
 * This makes it so a user who upgrades and runs their app can see their app
 * running and get the warning about the AppLoading module being removed
 * top, without an extraneous red screen that would appear from attempting to
 * render an undefined AppLoading component.
 *
 * Remove this in SDK 42.
