Fundamentally, conda is like a linux distro (or homebrew): it is cross-language package manager designed to work with a coherent set of packages (either via the anaconda channel or conda-forge). uv is currently a different installer for PyPI, which means inheriting all the positives and negatives of it. One of the negatives is the packages are not coherent, so everything needs to be vendored in such a way as to not interfere with other packages. Unless Astral wants to pay packagers to create a parallel ecosystem, uv cannot do this.
