Description

At the moment we build each release for all supported Python version at time of release.

Instead, we could build for the Stable ABI and have one wheel per platform instead of one per platform per python runtime and version.

The main benefit is that when a new Python version is available (beta, rc, released), one can use our existing wheel.

Another benefit is that release build time should be greatly reduced (currently more than 2 hours).

Research direction

Start by locating the release build configuration and the Python extension entry point, then compare the current per-runtime wheel matrix with the Stable ABI requirements linked in the issue. Done means producing one compatible wheel per platform, usable across supported Python versions, while confirming the release build no longer requires every runtime-specific build.
