I'm interested in this, but was never able to dive in to the lengthy discussions on this. I'm curious if there is a summary of the current state of things somewhere that I could read to catch up.

For those interested in continuing the __numpy_ufunc__ saga, there is a pull request enabling it https://github.com/numpy/numpy/pull/8247. Likely we will want to make some changes up front before merging that, so some discussion is in order.
As a first order of business, let's decide whether to remove the index and rename `__numpy_ufunc__`. The motivation for this is discussed in issue #5986. https://github.com/numpy/numpy/issues/5986 If we decide positive on that (I'm in favor), I would be happy with the proposed name `__array_ufunc__`, although something more descriptive like `__handle_ufunc__` might be better. This is a wonderful opportunity for bike shedding for those so inclined ;)
