As of two days ago, the minimum time thresholds for going through the definition and commitment phases of a proposal were changed. This change was announced one week ahead of the change.
In that announcement, there is the following text:
Going forward, we generally expect proposal authors to have the means to see their site ideas through.
Based on that text, I believe that these new requirements were only supposed to apply to new proposals created after the April 27 changes to the requirements.
Today, however, I noticed that a large amount of proposals (more than half the current ones) were closed for not meeting those requirements. It seems to me like those proposals were closed immediately without much warning, with the previous expectation that they would be closed one year later.
Also note that according to a comment on that question (emphasis mine):
This is incredibly unfair. After 6 months trying to get automotive people to follow an autonomous vehicle proposal, without warning, it's been shut down. In fact Robert was still recommending changes and closing questions he didn't like on our proposal until a few days ago. How in any world is this fair? It's like playing a game of football and the referee changes the rules five minutes before the end so the other team can win. Ridiculous!
Based on the above, were these changes supposed to occur retroactively to older proposals, or is this a bug? I'm just asking; I'm not asserting that it's a bug or that I think it's a bad idea.
