I'd like to avoid using "ES2017" as the baseline because nobody knows what it means. Seriously, there's so much confusion that it's just not a good way of framing the doc IMO.
Instead, I propose using ES6 as the baseline (since that's the big update that's well-known), and add individual syntax features in a list (both stable and proposed). At some point we can reset the baseline but I think for now it's nice to be explicit.
