Poetry seems to solve the dependency spec part, both for libraries that need to ship specs for supported version ranges of dependencies and apps that ship lock files.

However: poetry still falls short in managing the python runtime, I am continuously having to divert time to help our data scientists untangle the messes poetry makes with virtualenvs and their local python setups.

Also, they broke backwards compat on the lock file format? So now devs running newer poetry versions break projects for devs on older versions because the lock files aren’t compatible?!

Yes, I was very upset about the lockfile format change when we hit that; seemed like a very shortsighted thing to have done, but I guess I don't know the actual motivations or what was being achieved with it.
