Yikes! Do I understand correctly that you do not currently have anything working? My opinion is that this feature is too complicated and disruptive. My takeaway from the talk was "we got it to work, but it was a lot harder than we thought and probably wouldn't do it again". I think I can safely speak for most of the other openbsd developers that we are kind of scared of any large (or even small!) change to the softdep code. If this is a topic that interests you, I think the NetBSD wapbl is a simpler approach. There is even code in bitrig which can likely be made to work on openbsd. The softdep approach is very interesting, so don't let me stop you from studying it, but if you want something a little more "practical" I think there are better things to do.
