What exactly is your standard for "big"?

    $ du ~/.local/pipx/venvs/uv/bin/uv | cut -f 1
    38812

Stripped and dynamically linked, BTW. Compare the system-provided Python:

    $ du /usr/bin/python3.12 | cut -f 1
    7832

(But also, if you hope not to pay the cost of a Python runtime, what is your remaining use case for uv?)
