Sorry, I don't understand what you're saying, are you implying that once a feature (law) has been pushed into production (signed off) there can be no issues filed against such feature?
For this analogy, a bill should actually be a pull request and a signed law is a merged request. I think the problem is that an 'issue' should be a proposal, a bug report, etc. In this case, none of the 'issues' being created are intended to be closed.
