We ask for PR authors to avoid to rebase/update their PRs with the base branch (main) unnecessarily.

1. I'll check first, should I do a merge with upstream branch to resolve the conflicts? (The PR to add Volta has landed, and I expect we added code in lots of the same places.)

2. A merge will lead to the question, are the Community downloads in alphabetical order or in order added? 🤔
