Describe the bug
Python 3.15rc1 came out this week. Testing other packages that happen to depend on aiohttp with 3.15rc1 (which is important -- the Python core devs specifically request testing with this release) currently requires building aiohttp from source, which is a pain.
To Reproduce
Take for example github.com/microsoft/typeagent-py/. We're trying to prove that this builds with Python 3.15 but find that at least 5 packages need to be built from source; aiohttp is one of them.
uv run --python=3.15 python --version
shows that aiohttp is being built from source (at least the first time). (You also need to install rustc to build some other packages from scratch, notably tiktoken and pydantic-core.)
Expected behavior
It should download a wheel for 3.15.0
