It’s true that as releases get closer to final, more people will start exercising them. However, you really don’t have to wait. I maintain “official” Linux (Ubuntu) Docker images that contain all the latest releases (including alphas and betas), and the git head of the development branch at the time of the image builds.
https://gitlab.com/python-devs/ci-images/-/tree/master I keep these up-to-date on every new maintenance release, alpha, beta, rc, and final, for Python 2.7, and 3.4 through 3.10. I use this image in my own open source code’s CI, and you can too! Unfortunately, we can’t do the same with Windows, but I’ve cracked the nut to get pretty good coverage for Windows releases too. Here for example is flufl.lock’s .gitlab-ci.yml file: https://gitlab.com/warsaw/flufl.lock/-/blob/master/.gitlab-ci.yml I need to extend that to 3.9 pre-releases, via python.org downloads rather than nuget. So, it’s entirely possible to test your stuff against pre-release versions, and I highly encourage it. That said, I also think that the general rule of only bug fix changes post beta 1 is the right policy. For other changes, or anything that you think straddles the line between bug fix and non-bug fix, ask the Release Manager. The RM’s primary role at this time is to ensure the stability of the final release. Their judgement is critical to the success of the final release, so ask! CC the RM on the PR and request their approval and comment. I’ll also say that I personally give the RM a lot of latitude and authority to unilaterally revert any change they are not comfortable with. If the change author and RM cannot agree on whether a post-beta change is appropriate, you can escalate to the Steering Council.
