To call these situations equivalent is a little bit of a stretch. Per various insiders, Rise of the Resistance was always going to be December at the very earliest... it's just that Disney was originally going to hold back the entire land to open with it. We can debate whether or not they should have stayed with that original plan to open the complete land at one time (I believe they should have), but that is not the same thing as opening a ride and being unable to have it reach even close to its intended capacity on a daily basis months later.
If anything, Flight of Passage would be the closest modern comparison point, but even that I don't think is one-to-one.
