I think the answer to your question depends on the conclusion that may come after it. Like if it's "therefore, past May 15 we should all just act as we did pre-COVID", that's different than "therefore, that's overall very good news for society". There's a quantitative/qualitative thing going on here. We could be mostly "back to normal" in a broad numbers sense, while immuno-compromised people are left with a much more dangerous reality than they faced pre-COVID. They're left hoping for test/trace/eradication. Personally, I'll feel pretty safe hanging out, even in closed-in areas, with other vaccinated people. But out and about, the decision to wear a mask will be more predicated on the actual disease prevalence numbers in that area. And we'll all continue to wait on data of how long the vaccines last.
