Often there is a lot of discussion about a new feature-request and it lays around and won't get implemented not knowing if it is good or not.
Or the community really likes a feature, upvotes it a lot but the team is not so sure this would be a benefit for the site.
Would it be practical to try some feature-requests for a while and see if they work?
This would of course mainly apply to those not needing a lot of implementation. Take this request* for instance. It does not need a lot of work. It could run for a week and afterwards a little statistic could show if it did some good or not.
Would you say we should consider such a practice for some feature-requests?
Yes, it is one of mine. It is just an example.
