As a visually impaired person please don't. I like being able to resize text and still have the document flow properly instead of endlessly scrolling back and forth.

It's a Tagged PDF so supports reflow or extraction into HTML or text formats.

I'm a big fan of pdf/a but it doesn't support reflow, not in any sense that users would want or mean. Reading your post on a phone is awful.
