1) We don't know what the final rated Model 3 range will be. I remember Elon saying at least 215 miles. Was that referencing the upgrade option, or the potential for more range on the base battery? IDK. But just like the Bolt was "at least 200 miles" range initially, we'll just have to wait and see.
2) When I think of range greater than 200 miles, I'm thinking long distance driving. And when I think about long distance driving, the difference between 215 miles and 238 miles isn't as critical as the difference between Supercharging and CCS charging.
3) I'm fine with the Model 3 only having 215 miles range if it means hitting the $35K target. I'd rather they keep that promise ($35k target) than increase the base battery pack to win a false comparison of long-range capability and have to increase the base cost as a result. I'm confident Tesla won't bite. After all, that's what battery upgrade options are about, which the Bolt doesn't even offer.
All things said, I'm pretty impressed by the Bolt's specs, which are a great step forward for EVs as a whole. I doubt it affects the Model 3, but it should push improvements to the sub-150 miles range EVs (Leaf, i3, etc.).
