I have an explanation. Understand that common core was never about anything other than to turn the education system [into indoctrinating people everyone toward communism and Agenda 2030](https://invidio.us/watch?v=EywxzHBwofM). Now that they've accomplished many of the goals, another technique is to give people a pretend win while they shed some of the upfront issues in name while all the ideological programming has seeped in. Another example of how they do this is with Brexit. The people get their victory in name, but immigration and subversion toward Agenda 2030 is still not stopping for at least a year until they can find some other subversion angle. A third example is Trumps "build the wall" while he plays good cop, but the immigration "bad cop" activities are still pulled off by the Democrat party and they have more illegal immigration than ever, less deportations than ever, and very little traction on any new wall itself that hasn't actually replaced old wall.
