So it seems that something like 60% of the active modders actively dislike (at best!) the current trait system, which makes me wonder why this discussion hasn't happened earlier.
Probably because we are all busy on things and don't want to add more work

To improve the mod, I think you have to occasionally break save game compatability. Initially it only effects SVN users - most (not all), probably restart on a regular basis anyway.
Those that want to keep playing long games, do not need to update to the break save version.
I currently keep a version from last May and (an almost) up to date one.
To not do something, that is really needed, just because it breaks saved games. Seems the wrong approach IMO.
Most mods do not have save game forward compatibility. C2C does, it is one of the things that makes us different. Hence the reluctance to do something that breaks saves.
Having said that there are getting to be quite a number of things hanging around which could break save games that we want to be rid of. Perhaps we now have enough to consider the break.
