My opinion is that we will never see such features in ROS.
There are much more simple problems and features asked for years never done.
There is no reason to ask for these.
On the other hand, releasing an affordable platform for IPS/IDS functionality (with suricata perhaps) would be a very nice opportunity for Mikrotik to gain visibility, and thus boost sales.
Most of the other feature request I see here do not open a whole new market segment...
I do not (yet) have a CCR, but if suricata becomes available, that would change immediately.
I think I can convince others to do the same...
