Minor questions; still LGTM. Feedback I should have given last time though: I'm not sure if the debug flag should be about "callable" functions or just a flag to disable token checks. I feel like we'd want to disable token verification everywhere if we do it anywhere (not that I have another case in mind yet)

And for debug mode/emulator, right?

I think the comment is correct - this function will only be called internally. It will be executed in debug mode but will never be invoked directly.

Functions SDK now includes a debug mode that can be enabled via environment variables to operate in ways that's useful during development. See firebase/firebase-functions#983 for an example. We will turn on Debug Mode and enable `skipTokenVerification` feature on the Functions Emulator. This means that callable functions will decode but not verify the signature of Auth and App Check tokens which is more or less what the monkey-patching of Firebase Functions SDK achieves. For some function triggers, we will now rely on the debug mode instead of the monkey patching to bypass the token verification.

To replace monkey-patching of the Firebase Functions SDK in the Functions Emulator (code), we provide native support for bypassing token verification for
onCallhandlers.Using the new debug mode introduced in #992, Auth/App Check token included in the request will be decoded but no verified.
