I think there are other reasons (and I'm deriving these comments
from discussions with Eric Hansen):

1) All content must be available only to eyes, only to ears, and
only to fingertips. (Refer to my comments on grouping checkpoints
and the category of perception and the senses.)

2) Given the state of current technologies (that are readily available,
not too expensive, and accurate enough), text is the best way to
ensure that information can reach all of those senses. Text is not
ideal for communicating all information (graphics and audio are often a 
lot more effective than text, some users can't read visually displayed
text,
deaf non-readers seem to lose entirely in this model, etc.) However,
today's tools handle text characters as input much better than
images of text (OCR) or voice-to-text translation (although that seems
to be improving). How good is general visual-to-auditory translation?
Or auditory-to-visual?

Thus, I think the emphasis on text is not strictly bound to
assumptions of literacy but requirements to reach eyes, ears,
and fingertips.
