I can only really speak from personal experience, which ended 20 years ago, but our policy always was that it was a separate proceeding - so much so that I would not discuss it with the line prosecutor. We were a separate agency entirely (State AG, not DA or US Atty)
Sometimes we would agree to continuance when the defense asked for it (frequently), and sometimes we'd go first if they thought they'd need the money for defense expenses, which, frankly, was rare (I was usually dealing with major operators). I did coordinate with federal agencies and DOJ/AUSA), because they often had the same targets.
To assuage your soreness, I agree that local DAs and police agencies are more inclined to abuse the process and apply it to petty offenses, which is wrong, as I've stated. Our cases were based upon "ill gotten gains" - where we could establish they had insufficient income to support their lavish lifestyles. I had no qualms about taking their toys. It was more effective than prison for many, and kept them from financing bigger operations. One repeat offender used insurance fraud to finance his new operation, and another got popped for bankruptcy fraud.
