Part of the reason is support. Long ago Britton Lee[1] in fact provided an AST API mainly for tool vendors. They stopped doing that when one of their customers called them asking for help with the "GUIDE BY" clause. Nobody at BL knew what a "GUIDE BY" was since it was something implemented by the frontend, but that didn't matter to the customer.
