This sounds like QPyBind11 to me?

too close to 'Qt for Python' IMHO
Could be! even if it's a longer name, it's more descriptive.
Not really a Python API,

Jokes aside, I think there is a project
called "PyAnotherSide" :)

This idea, as you can see in the code
is to run Python code within C++ code,
quite different from the bindings, but hey, maybe an example is more clear.
With QtScrypt (Following the idea of the old QtScript module)
You can have C++ code, and at some point that evaluates Python code and get some result back, say:
qDebug() << "something, something" << e.evaluate("[i for i in range(10)]");
and you can get a QVariantList with the numerical values, same idea with a Python function, like:
you can call it from C++ like
QScryptFunction f("power_of_two", &mod);
qDebug() << "power_of_two(4): " << f.call(4); // you get 16 as a QVariant
PyQt and PySide
provide bindings Python for the Qt API,
button = QPushButton("press me!")
on Python files.

No worries, it's useful to ask things are are unknown to ourselves :)
So, as the original email states, this is for a 'playground' repository, because I was literally playing with this idea on a Hackathon, and after presenting it in some talks in Qt conferences/workshops, some folks thought it was something interesting to play with.
