Not sure what you are talking about:

    Promise.resolve().then(() => Promise.resolve().then(() => {throw new Error('Problem')})).catch((e) => console.log(e.message));

I have many large applications running on NodeJS 9.3.0 that rely on exceptions in promises for both control flow and error logging...no issues here.

Could you explain this? We use node everyday and I don't understand what you mean.

That doesn't make sense. That's one of the purposes of promises. The only escape hatch is to throw asynchronously which you just don't do.
