I think this is part of it, it did not help that during the process it got abandoned and that poetry filled the void. I liked pipenv from its user interface it just never got from the PoC stage to „polished“. The way forward would actually be to unify the dependency resolution mechanisms into a PIP implementation (iirc pip has drastically improved its dependency resolution in recent years) and converge the various projects.
