We’ve reached the point where Chromium is essentially the de-facto web standard because Chromium engineers do the lions’ share of feature testing and development,

Most of the web standards driven by Chromium are not particularly beneficial to the web, but are beneficial to Google. This is not an accident. It is how Google has made itself gatekeeper of the web while maintaining the facade of an open and standards-compliant browser.

This is not a good thing. Community-focused projects investing time and money into supporting it is a bit like digging one’s own grave.
