You are absolutely correct that it could be implemented as 100% a tweak to the parser.
Assuming filmor is correct, in practice as it happens to be implemented in the Python code base it is not 100% a tweak to the parser - changing the structure of the produced AST means tweaks down the line. I think the change to the parser is still the most meaningful piece, though, even there.
