Nah, it's not that bad. I built a Rust-backed Python library used by many [0], and with setuptools-rust (maturin wasn't flexible enough at the time) and cibuildwheel and GH actions, the wheels are built/shipped with the shared libraries embedded and the end user never has to worry or even be aware of its presence.
Pydantic has already been shipping a binary mode with an option for pure Python, so maybe they'll keep the pure Python mode around.

Disclaimer: I work for Temporal
1. yes. its on the order of months. start watching https://github.com/temporalio/sdk-python
2. temporal itself will not produce something like that, because we much rather have a lively community of third party maintainers/startups do that and be their supporters rather than competitors. interested?
