It's kind of odd that the consumer versions of Chrome and (especially) Firefox are loaded with developer-oriented features. I use these every day, but there's not a great reason for these to be in the main release.
Perhaps there is an opportunity for a developer-focused web browser with all the complicated bells and whistles. Or, a consumer-focused browser without them.
For example, in the last Android version you have to tap 7 time on the "Android version" field in the "About" screen to enable the developer menu. A casual user will never go there.
Or maybe just hide developer options in a about:developer menu.
Or perhaps they start as "consumers" and then learn development?
What happens to that process if you hide the things they could use to undertake it?
Then I, for one, would have never learned how to code.
