I agree with you that we don't have the evidence for dietary exposure. My polemic generalization in my earlier comment didn't make it clear that I was only speaking about "commercial and heavy-residential use", that is to say, people whose job or hobby it is to spray RoundUp for hundreds or even thousands of hours a year. Much like how you shouldn't weld without a mask, you shouldn't spray RoundUp without a mask. But the difference is that things that can be inhaled are very tricky compared to things that are just bright. So even the right precautions can still lead to problems. If someone who worked at a fiberglass plant told me not to breathe in fiberglass splinters, I would believe them, regardless of what the research has confirmed.
