This may be a stupid question, but I don't see the reason why this is the case.

I was running the following (essentially checking out matplotlib in a venv)

uv init example
cd example
uv add matplotlib

This created a new repo with a virtual environment.
When I was checking out example/.venv/lib/python3.13/site-packages/matplotlib I found the tests directory with a bunch of pytest files.
Basically, these files seem to be distributed.
I then ran du -h and found out that the tests alone amass to just about 2MB.
This seems to be a lot of wasted disk space.

Therefore, my questions.

• Are these tests actually used in the distributed package?
• Would it make sense to exclude them from the distribution, if they are not used by any user anyway?
