Feature request threads that don't respect the strict "one issue per thread" policy hardly ever get taken into account. This feeature request thread contains three issues rolled into one thread. I strongly doubt that devs will look into it in detail.
However, a complete re-design of the permission concept has been on the agenda for long anyway and has been requested often already.
The decision for one permission concept or the other will probably not be influenced by this thread, as it is not detailed enough in technical terms - it describes an ideal state in the words of an end user and not in the words of a coder, so it is not very usefull.
