[...] However, I want to make sure amd64 won't be dropped because of some random developer at a critical position not agreeing with that.
I don't think you can really overrule a future decision, however much you want to. It seems similar to trying to fix bugs before they occur, I think. We might want to do it, but it's almost impossible. There's always going to be a different way the bug could be introduced.
If you are trying to overrule particular past decisions, please include details about what the decisions are and, ideally, any public data on when and why they were made or even a note that there isn't any public data on that. Even just details of how you became aware of the bad decisions would help.
The current form of the proposal looks arguably invalid. Please redraft it, or withdraw it if you think it's no longer the best way forwards after seeing Chris Cheney's report.
