I honestly wasn't trying to be combative. I tried to make my comment just long enough to give context (showing my understanding of the solution and the assumptions I'm making). I'm not trying to interject my opinion, but see where my assumptions might be wrong. I agree long wandering threads are difficult to follow. I have little interest in new C++ build systems, but will jump in and contribute when I see a familiar problem I want to learn more about like managing sizable Python codebases. Python 2/3 isn't relevant at all to meson and I don't see the docs mentioning any need for version or package management. I've only ever heard/seen virtualenv needed in project management, never in distributed software. Is your beef with Python or any software using an interpreted language? Outside of the 2to3 transition and being deeply integrated in many distros, it has the fundamental problems other interpreted languages have and are handled in the same way.
