This is true to the extent that you actually _use_ all of the features of a dependency.
You only need to rewrite what you use, which for many (probably most) libraries will be 1% or less of it

Indeed. About 26% of the disk space for a freshly-installed copy of pip 25.2 for Python 3.13 comes from https://pypi.org/project/rich/ (and its otherwise-unneeded dependency https://pypi.org/project/Pygments/), "a Python library for rich text and beautiful formatting in the terminal", hardly any of the features of which are relevant to pip. This is in spite of an apparent manual tree-shaking effort (mostly on Pygments) — a separate installed copy of rich+Pygments is larger than pip. But even with that attempt, for example, there are hundreds of kilobytes taken up for a single giant mapping of "friendly" string names to literally thousands of emoji.
Another 20% or more is https://pypi.org/project/requests/ and its dependencies — this is an extremely popular project despite that the standard library already provides the ability to make HTTPS connections (people just hate the API that much). One of requests' dependencies is certifi, which is basically just a .pem file in Python package form. The vendored requests has not seen any tree-shaking as far as I can tell.
This sort of thing is a big part of why I'll be able to make PAPER much smaller.
What paper?
Presumably this: https://github.com/zahlman/paper
