I've seen a few ideas here that were unfortunately marked as status-declined. Does this mean that such an idea is a lost cause and arguing over it is pointless, or is it possible that the SE team may change it's views and make it a status-completed or status-planned, et cetera?
Some features are just blatantly never going to happen, like the various requests to have monetary rewards integrated into the site. People can keep requesting it, but that decline is never gonna change.
On the other hand, there are plenty of cases where a decline simply means "not right now." It's perfectly possible that it will be reconsidered at a later time, and there are cases where a previously declined feature has later been implemented. One example is the ability to retract close votes.
Features can be re-evaluated for a variety of reasons after initially being declined, such as:
- What wasn't a problem before is now becoming a consistent problem.
- Someone brings to light other factors not previously considered.
- Changes in the system make it much easier to implement another feature.
