You have missed the point(s): 1. As written, parsing ABNF requires arbitrarily-large lookahead 2. Because of the ambiguity, a parser which appears to be parsing ABNF (as that is specified) may in fact be parsing a different grammar (one without that ambiguity), and would not be suitable as a fully-conforming implementation for the purpose of advancement of the specification to Draft status.
