I can see that the status class (opened or closed) will end case role relationships, but is it used for anything else?
edit for clarification: Each case status has a "status class" - open is "opened" and resolved is "closed" by default. The only effect that changing a case status to resolved/closed that i can see, beyond that status, is that case role relationships are assigned an end date and so are inactive, so i'm wondering if this status class is used anywhere else that i've not noticed.
Reason being - i am considering removing "closed" status class from all status types, so that case role relationships are maintained whatever the status and can be ended manually if necessary instead.
