In a similar thread that was discussing Reclaim and why the server can't just "save the state" of your craft: part of the issue would be volume of data tracked when players only really care about losing a synth due to DC for stuff like:

1. 60 2-star recipes.
2. Maybe primal ex weapons (mog weapons)
3. Some furniture
4. Maybe some 1-star stuff like Thavnarian gear

They could "trigger" the server to save the state of that one craft when you talk to an NPC. It tracks just that one craft. Not every player on the server. I don't think that could be abused.
