No, I haven't heard yet because in Steemit, It linked to the profile pages by default when you add @ before any name but there is one way that you can achieve it. It is not a good way, but Might help you a bit.
Simply wrap the profile name within single backticks. e.g: @dasskelett. It adds the text within <code></code> tag.
