What is the benefit of reposting ideas that may be implemented several years later and discussed several times? As long as there is one developer I do not think that such topics will change anything.
If the topic is about the changes that have already taken place, that may be meaningful.
Let me explain it more. I started with ideas that sometimes theymos posted excellent posts (as he always does), but he did not create new topics to do it, they are just posts. In addition, those posts ususally published in massive topic in Meta board, it means those posts will highly been burried with future posts from forum members. Overtime, people even don't know or forget that those posts exist in the forum. Consequently, discussions on such innovative changes are very limited.
That's is why I created the topic, to remind forum members that theymos raised something for us to discuss, and where to join those discussions.
