I think reducing redundant code can make it simpler for developers to understand the code base, and I would like to work on this issue.

Yes. webhooks used to be called from chrome itself so that that time config was needed there, earlier version of puppeteer wasn't supporting direct code injection so had to write util for that.

Feel free to make a PR for whatever you think is extra or unused.
