  To what end though? We are in full agreement that we don't want preambles for source files that aren't open.
  
  Our discussion is about when to create the preamble for open documents. If I were to stop that job, I wouldn't get the AST, but I want the AST. I just don't want the preamble before I've started editing the file.
