I misunderstood the point of this comment before, thinking you were arguing that MIDI fails because it is not, itself, a clear human-legible format like text-notation languages being discussed are.
I understand now that you likely meant that MIDI does not capture the score itself, so it does not work as a notation file format, whereas these text-notation languages do describe the score.
