Existing debt is currently handled in a debt queue structure. If you ignore a suggestion once it will remember that and store it in that queue so that it doesn't bring it up again. There is a mechanism to review that queue but I haven't totally thought out how to resurface those in a convenient manner.
There are obvious solutions like dumping those ignored changes to Jira issues so you have a pipeline of debt to address though I feel like this just moves the issue so I'm trying to think of something more proactive.
It's very similar to those with two key distinctions. Ox aims to be more simple in it's behavior to not add work to the review process and this approach allows Ox to operate more cheaply while delivering everything competitors do. In sum it is more simple (on purpose).
