They can be slow to adopt changes. I think the Mozilla foundation getting more funding, staffing, and refocusing on their browser would be the better solution.
While Chromium is an open source project, it is still developed and maintained by Google. For something as important as a web browser, I think it’s imperative that there’s an option outside of their control.
To an extent. But it wouldn’t surprise me at all if sometime in the near future they force the use their own DNS servers within their browser instead of respecting your network configuration.
The best solution to circumventing Chrome’s bad behavior is to not use it.
