These feature requests have been marked as NeedsARethink and been put aside because they don't fit the typical TWiki community.
This does not necessarily mean that the idea is bad. It could be that the way it has been proposed or implemented (if it got that far) is not suitable for inclusion into the TWiki Core.
There are three options at this point:
It can either be rewritten to try and achive the same utility in different way, in which case it's CurrentState should be changed back to UnderInvestigation.
If the feature request was submitted because of a misunderstanding due to insufficient documentation it could be changed to a DocRequest (use the form on the DocRequest topic or copy the DocRequestTopicTemplate into the topic and refactor).
