The support patches look good overall.

They remain in pending status because they primarily add new files that aren't being used anywhere yet. This means we can't fully test them right now due to lack of usage. They might not be in a fully working state.

These patches can be merged either:

• At the final step of updating test.support
• When other code begins to require these files

Generally, keeping patches unmerged is not ideal since conflicts gradually increase over time and patches become outdated.
However, in this specific case, since these patches are mostly adding new files (which typically don't create merge conflicts), I believe there's an exception where keeping them unmerged temporarily offers more benefits than merging them prematurely.
