This seems aimed squarely at VSCode. VSCode does a lot of this now out of the box (or with a few extensions). I think Atom is really just trying to keep up. I personally do not believe they have the horsepower to compete with Microsoft here though. VSCode is a phenomenal product.
I want a text editor that vaguely understands code with some simple file browsing and plug and play extensions. Atom trying to become VSCode isn't beneficial here at all.
