I would say uv provides quite a lot of additional features that can be used in various ways to create plain-old venvs. Note, however that uv-pack can also pack a subset of your uv-monorepo for a specific package (there are still some quirks I have to admit..). My experience was that it‘s surprisingly painful to „just copy“ a venv and especially a uv-created venv. There are a lot of paths to be modified to get the venv working. Copying a venv felt hacky and wrong, that‘s why I built the tool :)
