I will echo Matthias here. We just spent multiple months working out this new process. In order to make it work, people need to help make judgements about which of these PRs should proceed and be included in Sage.
I understand that participating in these particular PRs can be daunting: the people involved have strongly held opinions, many of the issues involved are technical, and the comment history on some of these PRs is very long. I especially encourage those of you with substantial packaging background to help resolve these PRs, but other developers are welcome to participate in voting as well.
