The code performs really well because, as you say, they've done a great job engineering it. However, they've specifically stated a few cases where C++ wasn't pursued. An example: A while back I read a blog post [1] talking about how they analyzed why the text buffer was causing OOM errors for certain files. It's a really good read, discussing drawbacks of the initial array of lines data structure, and how they came to use the "piece tree" data structure, and some of the tradeoffs therein.
