The more influence Google gets over the web standards, the more they will steer it in order to raise the barrier of entry for web engine makers. It will also get them more and more power over what can be commercially viable on the web. Making it easier for them to set the rules for everyone on the web seems directly detrimental to your business. As time passes by for Brave to became "big enough" (supposedly to develop a 2020 state of the art web engine), the complexity of starting a new engine from scratch would continue to grow.

It seems that keeping Gecko up to date with the web standards is the only way to have an concurrent implementation for mid-term. This will get more and more difficult to do the more marketshare Blink gets, since it gets easier for Google to shoehorn whatever they want in the web standards by first making it a "de-facto" standard by implementing it in Blink.

This happens already, e.g. AirBnB deploys new content that breaks in Firefox (perhaps not totally; could be cosmetic or a corner case). Webdevs do not test in low share browsers.

Find "slow forking" elsewhere to see my response to your concern that we would have to make an entirely new engine from scratch this year or next. That's not the threat. We strip out Google tracking already and work in W3C to keep them from jamming premature standards through -- if they try turning any such on without other browsers agreeing, we will disable.
