They do touch on these issues but only barely. The survey is more about who's using Go the way it is now and how can we help with adoption with what Go is. The survey is not necessarily intended to be a how might we make the Go core language different or "better" sort of thing. Remember, for a lot of Go developers Go _is_ fine the way it is now. You may get a different set of developers if you add features but you also may lose those who like it the way it is now. There are a lot of applications coded that just don't have a need for the features you mention.
