I think that when you, as most HN commenters are wont to do, are trying to achieve a certain level of mastery in your craft, you're going to want to dive deep, understand the abstractions, have full control, be able to start with nothing but a UDP socket and a steady hand, but that approach misses a huge number of users of these languages. You don't want scientists to have to worry about setting up a venv, you want them to analyze their data and move on with their lives. Sure, people like you or me will be able to setup and source a venv in no time, without expending much mental energy, but we're not who this product is for. It's for the rest of the users, the 99% who aren't even aware places like this exist. All that said, I'm pretty skeptical of using uv until their monetization strategy is clear. The current setup is making me think we're in for a Docker-like license change.
