I mean, Ruby was created in 1995, Python in 1991. Node was first released in 2009. That's not an entirely fair comparison since, of course, JavaScript was created long before Node, but Node introduced the language to a new environment, and a lot of complications needed (and in some cases, still need) to be sorted out.
As for no recommend approach - that's deliberate. I don't think most people working on Node want a Rails equivalent.
