I've switched from ruby-vim-linux back to java-ide-windows 2 years ago, while of course being a `downgrade` in a certain sense, having Intellij was A BLESSING, the VIM mode is very good and although of course I had to change some stuff in my workflow, I was surprised by how good and smooth the tool is and that I didn't feel "held back". I would consider using Intellij IDEs for other languages even if they're not "IDE oriented", there's no comparison between it and any other IDE I've used before(I make sure to point out to colleagues on Eclipse that they're cavemen to me and that my tool is like the sharpest fancy-Cook-knife and theirs is an old-blind-bread-knife and it's a piece of trash). Seriously, I consider it one of the best pieces of software I've seen and I plan on studying it's program design and code someday. Answering your question, well, that's what they do, they have a lot skin in the `editor` and `developer tool` game and also a lot of stuff to build on top, so it's not a surprise they want to 'serve' a lot of languages. I don't know about Go specifically but I'd guess even if not 'filling a need' I'd think possible that they are capable of discovering ways of smoothing out the experience or something, which is valuable.
