CodeDJ "Really would have been nice to point this happening though. I had figured that was what it was but figured it was to early to start. Assumed they would wait at least till beta flighting to do this."
It has been clear for a while (based on a number of articles I've read in the technical/trade press) that Microsoft intends to make Edge Chromium the default Windows browser beginning with 20H1. Although I wasn't aware of the article you linked, it doesn't surprise me that Microsoft has moved Edge Chromium to default status in the Windows Insider builds.
Isn't the more relevant question, though, where 20H1 is along the alpha-beta path than where Edge Chromium is along that path? After all, 20H1 is predicted to be a major release (unlike the "service pack" release coming this fall), and it seems to me that the sooner Microsoft starts testing Edge Chromium against 20H1, the better.
I'm not a active Windows Insider at present, though, so I defer to those who are testing 20H1.
