- Migrating the HTTP[S] mock from relying on `http-parser` to `httptools`.
- Never discovered the root cause for the failing tests with `aiohttp`/Python 3.11 (first time ever I added `pytest.mark.xfail` to a few tests). Same test works with `httpx`, so I suspect it's related to a client issue. I'll probably migrate to `httpx` as the reference client for testing `async/await` code.
