Conda dev lead here. Agreed that python has needed the pipenv concepts for a long time, even though they're not really all that novel in the world of software engineering. Bundler, npm, yarn, cargo, etc. have all cemented the two-file idea of environment descriptions. One file that is a minimal description of the environment, designed to maximize portability, and one file that is a maximal description of the environment, designed to maximized reproducibility. It's also long overdue for conda, and we'll be implementing the pattern soon. See https://github.com/conda/conda/issues/7248 https://github.com/conda/conda/issues/7248.
