I mean, in all honesty, EdgeHTML wasn't ever really an engine that had much hope. IE has always been loathed, Edge just continued that trend. Their marketshare wasn't great, and tying browser updates to the OS as they did with IE was irresponsible for how browsers are shipped these days.

If Edge had 35% marketshare I'd be more concerned, but nobody was using it, and web developers hated trying to make their sites compatible.

Good riddance to IE/Edge of old :)
