Re: [rules-users] From v 3.0.6 to 4.0.0

I can't remember them, but at the time we where shown some use cases that worked that way. Also we have the problem that our engine works differently to other engines, so we decided align with the industry norm and allow people to choose what they want. Oh and identity removal has a slight performance impact, as it means it always has to performane an identity check on each join attempt, even if the scenario will never likely occur for the current rule definition.
