It's more complex and heavier than using uv. I see docker/vm/vagrant/etc as something as something I reach for when the environment I want is too big, too fancy or too nondeterministic to manually set up locally; but the entire point is that "plain Python with some dependencies" really shouldn't qualify as any of these (just like build environment for a random Rust library).

Also, what do you do when you want your to locally test your codebase across many Python versions? Do you keep track of several different containers? If you start writing some tool to wrap that, you're back at square one.
