Too often, threads that are bug reports require actual discussion. Many users don’t know the definition of a bug to begin with and discussion amongst users might be able differentiate what might be an unrelated issue, including misunderstandings about how things are supposed to work (the “feature/not a bug”) or perhaps bad data (bug or no?). The other overriding issue is that bugs change and evolve over time as fixes and tools are created to mitigate them.
Additionally, forum searches and even recommended threads steer us toward these bug reports, which are not always blatantly obvious as such. Things also get reclassified after discussion already begins. But once bug tagged, any further discussion, even if relevant, gets shut down.
I understand that the bug threads are maintained so that devs can do their dev processes. So it would be helpful for every “bug” thread to have a parallel, linked discussion thread that doesn’t interfere with bug discussion and dev processes.
