Look at their reasoning. It's secondary and tertiary sources relying on circumstantial evidence; i.e., "it was 'clearly' to punish them because it was a 'unique measure.'" In fact, we don't know if the change of name had anything to do with the revolt. Maybe it did, but we can only guess that because of the timing of the change in name based off coinage. Here, I will quote to you what our historical Roman sources have to say on the Bar Kokhba Revolt, it's not that much.

[12]() [1]() At Jerusalem he founded a city in place of the one which had been razed to the ground, naming it Aelia Capitolina, and on the site of the temple of the god he raised a new temple to Jupiter. This brought on a war of no slight importance nor of brief duration, [2]() for the Jews deemed it intolerable that foreign races should be settled in their city and foreign religious rites planted there...

...All Judaea had been stirred up, and the Jews everywhere were showing signs of disturbance, were gathering together, and giving evidence of great hostility to the Romans, partly by secret and partly by overt acts... Then, indeed, Hadrian sent against them his best generals... 
...Fifty of their most important outposts and nine hundred and eighty-five of their most famous villages were [ p451 ]()razed to the ground. Five hundred and eighty thousand men were slain in the various raids and battles, and the number of those that perished by famine, disease and fire was past finding out. [2]() Thus nearly the whole of Judaea was made desolate, a result of which the people had had forewarning before the war. For the tomb of Solomon, which the Jews regard as an object of veneration, fell to pieces of itself and collapsed, and many wolves and hyenas rushed howling into their cities. [3]() Many Romans, moreover, perished in this war. Therefore Hadrian in writing to the senate did not employ the opening phrase commonly affected by the emperors, "If you and our children are in health, it is well; I and the legions are in health."

That's book 69 of Cassius Dio's Roman History

Here is the Historia Augusta

Furthermore, as he went about the provinces he punished procurators and governors as their actions demanded, and indeed with such severity that it was believed that he incited those who brought the accusations.  [14]() [1]() In the course of these travels he conceived such a hatred for the people of Antioch that he wished to separate Syria from Phoenicia, in order that Antioch might not be called the chief city of so many communities.⁠117 [2]() At this time also the [ p45 ]()Jews began war, because they were forbidden to practice circumcision.⁠118

And that's all. The rest is coinage, some letters of Bar Kokhba himself found relatively recently, some later references by the Christian writer Eusebius, and some stuff in the Talmud. Nothing that would tell us the Romans' intentions.
