The intention is for all posts to get looked at. The suggestion is locked as it isn't the intention for every suggestion to be talked about incessantly so that there are five ideas with 12 additional posts making it unwieldy.
To use the now infamous suggestion about II, the suggestion, "I think the folders should be open is enough to encourage discussion. It isn't discussion so much by the CAB as the users can discuss on the board. It is to get the idea to the very top.
This isn't perfect. It hasn't been done before. The administration brought it up. Who knows? May not work.
At least it provides one more thing for users to complain about.
