It is my understanding that this is still the previous developer program

enabled for the new Simple Content Access thing.
This is not an official statement, j
to note something which I hadn't realized before:
this subscription includes the "EUS" offering which provides security
updates to select minor releases (so you can "pin" to that minor release),
which is something CentOS never did.
