Yes, PATH-driven interpreter selection is the source of the detours. uv eliminates interpreter ambiguity but requires uv as a prerequisite. This improves portability inside environments that standardize uv; it’s not “portable to machines with nothing installed.”

Though, this isn’t about avoiding installs; it’s about making the one install (uv) the only thing you have to get right, instead of debugging whatever python means today.

I was advocating for containers as the “hard isolation / full stack” solution which eliminate host interpreter ambiguity and OS drift by running everything inside a pinned image. But you do need podman and have the permissions set right on it.
