Abandonware? PS and its 3D engine CS is far from being abandonware. There are periods of activity and inactivity, like with every hobby. If people are not active for a month or year, it doesn't mean they won't ever come back.
Regarding names I have proposed nearly the same thing 3 years ago. I'm still here and haven't forgotten about it. Postponed doesn't mean it won't ever become real. I don't see it as a huge issue personally, thus other things take priority for me.
I personally dislike the fighting system as it is now. Network lag causes those stupid messages that don't even correlate to what the server calculates. But on the other side I have seen the system as it was before and without the messages it wasn't better. From the technical side, it is very hard to eliminate lag as factor. Commercial games can try to tackle that with a multiserver-architecture with the client using the geologically nearest server. PS doesn't have multiple servers, but that might change in future.
Also your point on turning speed is granted, but I disagree with your complaints regarding camera view. I very much like the camera freedom and the modes as they are.
Regarding your point on collision detection: yes, a lot is possible there, but no, it's not easy. CD is one of the most resource-intensive things there are. Take into consideration we don't have a serverfarm running in the background, only one machine that handles everything. That's a very challenging setup requiring creative solutions and time to work them out.
CS already has been used for commercial applications. As example, it was used as test environment for a semi-automatic stirring software for RL trucks.
