The problem is that we cannot change how darcs 2.5 (or 2.4) reads _darcs/format, so we cannot afford to have a "new semantics" alternative with already known properties (for instance, no darcs3|hashed). That should not be an insurmontable problem, given that darcs 2.5 understands very few format strings, but it is bug prone.
