Simply having modern RAM capacity helps, because authors can add many more synonyms in their code to handle various player inputs. The early parsers were constrained by having to run in tiny RAM spaces (64k, 128k, 256k); expanding vocabulary was difficult to do without removing space for description text and other important game data. In Inform 7, when targeting the glulx VM the memory limits are much larger (i.e., the sizes we expect today) and you can define synonyms to your heart's content.
