On per-site metas we sometimes need to close the following two types of questions:
The question was related to a project or contest with a particular duration, and that time has passed.
The question was about something that the community needed to decide, and a decision was made and implemented.
In both cases we want to close these questions to fend off new answers. In the latter case, if a decision needs to be revisited we want a new question that takes the history into account, not new answers to a two-year-old question.
We used to use "too localized" for this (at least on the sites I frequent). Now that "too localized" isn't available as a reason, what close reason should we use for such questions? None of the default options seem appropriate -- it's not off-topic, not unclear, not too broad. (I'm discounting "primarily opinion-based" as that's a lot of what's valid on metas, so it would be ironic to use it here.)
