("More mainstream" is a moving goalpost fallacy.)
Of course the "mainstreamity" of languages is hard to determine, but Dart is so low in any kind of related metric that makes this a non-issue.
Let's put it this way: the Dart team announced a few months ago that they'd be concentrating on transpiling [1] and they won't put the VM officially in Chrome, and nobody gave much of a fuck judging from reactions in blogs, forums, HN etc.
If a mainstream language changed something, even something minor, there would have been blood (as it often happens).

I don't at all mind your saying so, but it might be frowned on around here.

Why can't you read?
If I write songs that sound like Taylor Swift but no one knows who I am, do I make "mainstream" music? Personally, I would say yes.
