As far I remember, JRules does.
And it could be great to add/restore this possibility in drools (is 
there a JIRA somewhere where we can vote?).

For Marc's question, I think there could be a confusion between a 
production/inference system like drools, and something that looks like a 
database trigger. And yes, if you really want to detect fields changes 
individually, fields must be inserted as individual objects in the WM.
