Even though I am an impatient person, it’s not because of #1 or #2. Part of it is to prove it works in nova. But I think the main reasoning behind most of them are because nova already has most of the duplicated code, and in order to let us use o.vo, there needs to be a slight change to it. So my steps in committing to both are 1) fix it in nova’s duplicated code, 2) fix it in o.vo 3) get the change merged/released in o.vo 4) eliminate all duped code from nova, cut over completely to o.vo.

So the main reasons are forks and to answer the question “why does o.vo need this?”. The change this thread discusses doesn’t fall under this realm, we know why we need/want it. But my situations are just a data point to add towards carrying it in both places isn’t the end of the world (though I’m not saying this approach is the best way to do it).

I would totally agree, if o.vo was purely upstream of nova. Unfortunately, nova is still carrying a lot of leftovers, and because of the “forks” I need to push something to both of them so I can bring them together in the future. I’m doing my best at bringing these two closer together.
