I'm not sure. I think it was mostly a historical artifact. Originally there
was only the simplified AST, at some point the AST was augmented with
source locations but the simplified tree was not removed for backwards
compatability. Some of the library still operated on the old simpler AST
such as the pretty printer but now everything is ported over.
