> Unclear what specific specs you are trying to throw under the bus here.
Almost all the hardware specs (most of which are "not on any standards track", shipped in Chrome), things like Backround Fetch and Background Sync (same).
There are also others that Google shipped even before there was consensus and there were glaring issues in the spec (like Constructible Stylesheets)

To call this a misrepresentation of reality is a gross understatement
