Instead of "Reference counting primer" I would like to see a primer on how exactly such a huge change can go into Python without formal PIP process.

Because it's an implementation detail, not a change to the language itself. Similarly, when they re-implemented the dict type to preserve insert order, they also introduced it without a pep, because it was a side-effect of an implementation detail. Only later they decided people are so likely to depend on this, that they formalized it through a PEP.
