For example, if you're not careful to avoid dependency loops, you'll create a program that will never terminate. You'll need to recursively query Requires from those BuildRequired packages, but you also need to map those their respective source packages, and continue with querying BuildRequires recursively. I've tried to write a script that does that, but it doesn't provide correct results yet.

I would appreciate it if you actually read the proposal instead of making personal attacks like this: The proposal does not create a mandate for package maintainers for dropping i686 from packages at all. The goal is to make it easier for maintainers if they are already thinking about dropping i686 from their package. I will also provide a list of potential candidate packages, but it will still be up to the maintainers whether they incorporate or ignore this change. So I don't understand how this "puts virtually all the effort on the maintainers of the majority of those packages", if completely ignoring the Change and/or inaction are both perfectly valid choices.
