It's not just fear of Google and Chromium beating EdgeHTML that's driving this. It's also Apple and their iDevices. This allows them to bring Edge to parity with Chrome, and by building their own features and proposals on top of that they regain the ability to drive standards. But they can also errode Apple's moat by supporting web standards and deep device/native integration better than Safari, which lags chromium in standards support.
