Accessibility section

I love the new accessibility section of the curriculum. As someone with visual issues, but who doesn’t use a screen reader, could there be a task which places emphasis on checking that text re-sizes proportionately and the webpage is still usable if the user has specified larger fonts in their browser or phone/tablet? I’m not just talking about bumping up to say 18pt or 20pt but bumping up massively, to the maximum size say an iPad will go.

I’m not sure how exactly you can create a test for this, but it is often a shortcoming of websites (and apps) which I think needs more awareness from developers.
