I took a quick look and it seems "interrogating core for the versions" works only for the test in test_editable_builder.py. In test_factory.py it's not all versions from AVAILABLE_PYTHONS, but only the versions which are supported by the project. So it's actually reimplementing all_classifiers (or comparing it to itself). Thus, maybe just keep it hardcoded in both places.

I came to the same conclusion as @radoering, but forget to answer.

The backport to 1.2 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-1.2 1.2
# Navigate to the new working tree
cd .worktrees/backport-1.2
# Create a new branch
git switch --create backport-6561-to-1.2
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 f8ecaca63bd17d5308fbaa2394575d3933d98349
# Push it to GitHub
git push --set-upstream origin backport-6561-to-1.2
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-1.2

Then, create a pull request where the base branch is 1.2 and the compare/head branch is backport-6561-to-1.2.
