I have a habit (which begot a policy) to push test cases for
issues regardless of existing test coverage. I assume one can
change independently of the other in the future, and we need to be
able to quickly navigate from a ticket to a test, e.g. when
dealing with a duplicate ticket or tracking down a regression.

Perhaps it's a bad idea after all, we can discuss.
