Usually "roadmap" implies there is a schedule, and "on the roadmap" means an item is on the schedule. Also, to "plan" means to decide on and arrange in advance. This suggestion is apparently not on any roadmap. There is apparently no plan to address it in the future, unless the plan is just to periodically update the description to talk about other (unrelated) issues which were worked on instead. What's the point of that, other than to keep our hopes up longer, only to be ultimately disappointed?
Atlassian, please be honest and do not continue to say this is on your roadmap unless it really is. If it is, show us the roadmap, the schedule of when it will be addressed. Otherwise, close this issue with "will not fix", or at least "duly noted". It's really not cool to keep a suggestion open for so long (7 years!!) and not make a decision about it one way or another. If for some reason you later have a change of heart, certainly you can reopen the issue at that time.
