Problem

Wheels are extremely important for the Python ecosystem, and especially the scientific subsection. Newer Python versions offer many benefits, like new features and faster performance. On the release of a new Python version, for many packages wheels are unfortunately often not immediately available for that version.

This is a problem with many aspects, and in this feature request a system is proposed to partly but significant improve this situations.

The Python annual release cycle, as described in PEP 602, knows 3 phases. In the Alpha phase new features are added and bugs are fixed, during 7 months. The 3-month Beta phase allows for bug fixes. The 2-month release candidate phase is not clearly described in PEP 602, but practically only essential bugs and security issues are fixed. Historically, it also starts the ABI-stable phase for that minor Python version (Python 3.10.0rc1 | [3.11.0rc1](https://ww
