Proposals which have been dropped, or moved "off the table" after a period of discussion, are either moved into CategoryOldMeatballWikiProposal?, or deleted.
If the impact of a proposal is large enough for it to make it into this category at all, there should be a few months (or longer) between the proposal and the decision, to allow community members who are "away" a chance to see it.
Suggestions which either aren't too important, or won't have much dissent, or don't require a quasi-synchronous community decision, should be put in CategoryMeatballWikiSuggestion instead.
