Sometimes they are spun. Here's how Copenhagen Suborbital spins theirs, which is also a two wall design.
This is exactly what I thought about when I read "rocket nozzle".
When in production, we had a few parts with similar features that we ran on CNC. They were a time consuming challenge. Seems like every other month we would experiment with some new wonder tooling, which was able to better cut such features.
On this piece you have above, I would start on the righthand side ID and drill, then bore straight into the other chamber. I would then use a boring bar with the compound to start the angle in the large chamber to the left. Before removing the workpiece, the external nozzle features would be finished.
Then flip the part and finish out the chamber.
