Hey, Wesley! This is totally valid feedback and thanks for sharing it. This feature is currently in the pipeline and we plan to release it early next week.
Besides that, we have a status called #closed which is similar to #deleted. This status can be used for duplicate posts or features that are not relevant or created by mistake. At the moment #closed posts also appear on the boards, but eventually, they wouldn't, until someone explicitly filters for #closed posts.

Users who add a post might write a specific use case instead of generalize the feature request. In that case a staff user have to moderate the post so the feature request is more general.
Also a staff user should be able to delete posts (mark as #deleted) or mark them as #duplicate.
