Wrong place to ask this. Try the corporate contacts, pre-sales or AMD support directly. Google is the only other option. It stands to reason if you need Threadripper cores, than stick with that. The CPU's function entirely different, the 5950X is a high end desktop CPU.
The TRX40's are for servers, enterprise computing, intense CPU applications with a lot of threads, commercial grade stuff. I wouldn't even consider one for gaming. The 5950X can game but it's on that fine line of high workload over gaming performance and the 5900x is the best for both work/play, as it leans hard into gaming, yet can do some pretty crazy workloads.
Socket life, I think the AM4 platform has about 5 years left in it. TRX40, if they change the architecture, they may change the socket as well. Given it's been in use longer than the AM4, it most likely will change but how soon?
