The initially empty ast.StdAst was created to break the circular dependency. The generation of stdlib AST used to depend on the primary "jsonnet" package, which meant that "jsonnet" could not depend on it directly. Hence stdlib needed to be put in the ast package. Now dumpstdlibast no longer depends on Jsonnet, so we can get rid of this complication. All code using ast.StdAst should now use astgen.StdAst.
