Deleting a branch is permanent. Although the deleted branch may exist for a short time before cleaning up, in most cases it CANNOT be undone. Continue?
This document lists what needs to be done to get an initial version of Particle Nodes in master. The merge is currently scheduled to be part of Blender 2.82.
The function branch consists of four main parts:
Libraries
While I have some changes planned (especially for the hash maps/sets), this code can go in at any time. A significant portion of this code is covered by unit tests. I happily continue improving and maintaining it when it is in master.
Also see:
Nodes UI
As mentioned, nodes are currently implemented in Python. I happily move this to C/C++ at some point, but it does not seem worth it right now.
Also see:
Functions
The function system consists of a couple of components which can be categorized into:
The backend can be merged as soon as the libraries are merged. It should not impact anything else.
For the frontend to make sense, the node ui needs to be merged as well. This could be merged without actually exposing a new node tree type to the user.
Currently, there are also two new modifiers that I use for testing of the function system. I do not expect them to be merged.
Also see:
Particle System
While these other parts could almost be merged as they are, I have to spend more time on the actual particle system.
One particle simulation backend that is sufficient for a variety of particle effects is working, but the user interface is still lacking.
These things still have to be worked out:
Possible compromises to get this to merge sooner (not saying that we should not do these things, but we might need to trade-off features vs. time-to-market here):

I absolutely love the amount of information you're making available about how these systems work/will work and how everything is coming along. I played around with the build yesterday and it looked pretty awesome! ^^ I managed to make some particles bounce off a plane :)
I feel like to answer some of these questions, you should put a "beta version" in front of artists, and advertise it(Blender Today), and see what they do with it and what they have to say about it.
My understanding was always that this is planned to be merged no sooner than 2.82, if we are lucky. It sounds like you want to get it in sooner, but I for one, am happy to wait for something that's more polished. Take your time man.

The compromises to get this in sooner seem a bit harsh in my book, so waiting until 2.82 at the earliest (especially with the 3 month release schedule) appears reasonable.

Particle nodes will be worked on again as part of geometry nodes.
