When Microsoft decided to cede the browser to Chrome with Edge it was clear they don't believe a browser to be an important part of their current strategy.
If they had wanted to stop IE but keep competing they would have made Edge a Gecko-based browser and worked on it.
I think that Gecko is more dead than IE 11, 3% of people use it, versus 0.3% using IE11, but those Gecko people will move to chrome, while the 0.3% people using IE11 will never move due to enterprise reasons.
