Why is maturin ignoring my compatibility config when called with uv build --wheel ?

[dedebenui]

I'm using uv and maturin for a project, and I want to use uv to build wheels. In my pyproject.toml, I wrote:

[tool.maturin]
python-source = "python"
module-name = "propoptics._lib_propoptics"
features = ["pyo3/extension-module"]
compatibility = "manylinux_2_34"

but maturing still gets called with --compatibility off when calling uv build --wheel. Why is Maturing ignoring my config? According to this, it's not done on uv's side. It's not a big deal since maturin build works fine, but I was just wondering
