I'm 100% certain people use the utils stuff, it is useful for at least 2 common scenarios:

• do I have Play Services? (because if you are on Huawei or similar device you don't, and you need to either instruct the user about missing functionality or work very differently...)
• am I running in the Test Lab? (because if you are in the test lab, you probably want to disable certain stuff like app-distribution updates, analytics, maybe other stuff...)

link to actually useful docs is https://rnfirebase.io/app/utils (the typedoc render of it is awful / useless)

It's typed pretty rough though from a typescript and typedoc perspect and there may be a better way to expose this functionality. It does need a home though IMHO

Yeah, I left it because I thought it was useful but I was caught in a bind between utility vs matching v9 API. So thought I'd pose the question.

FYI; Tests won't pass here until Crashlytics is merged as there's an e2e test that uses console.warn 👍

LGTM!
