I like how we got these things done early in the process: - termed the proposal as 'improve password policy', in the subject, implying that the solution is good - instead of asking how to do it - put a single proposal, raising the requirement, instead of putting a few proposed changes and asking which one people would like to pick
My feeling is that there should be some guidelines, encouraging to shape questions and ask how to do things rather than propose a single change. It's what happens anyway, and putting it right the first time could be less confusing and encourage feedback by claiming an open question with suggested alternative solutions.
