Summary:
Do we need this? Is it possible for any of these codepaths to execute in production? If so, it would be nice to avoid NPEs or even scheduling work on the UI thread.
Maybe we want to add soft exception logging for if these paths are called?
Changelog: [Internal] make sure LogBox does even less work when it's not hooked up
