Since the packaging wars end of 2012 to beginning of 2013 I was following relatively closely packaging and requirements tracking, and let me say this: We don't need another solution. We need the solution we have to work better. Pip+Virtualenv is enough to learn and handle and nowadays works well for most use cases. It's maybe not perfect but it gets the job done. Problems I still see: Most of all integration with the system's package manager; pip3 install -e will be overwritten by the corresponding pypi package if you increase the version, although the -e installed version is already the required one; sudo pip3 freeze doesn't work, at least on the current Ubuntu. There are so many little details that need to be fleshed out in such an infrastructure tool, we can't solve all these boring problems multiple times.
