There's been plenty of threads that go like this:
Drupal user: "I want Forum X to integrate with Drupal!"
Drupal dev: "No, we'd rather just improve our own forums."
I side with those who would rather see a stronger native forums module for Drupal. But at the same time, I kinda agree with those who say Drupal's forum isn't moving forward much. (Glancing at the current 4.7 list, I don't see anything forum-related. Forgive me if there's anything I just haven't heard about.)
I'm considering converting my own forum (currently running phpBB) over to Drupal. To get a better idea of what it would be like if I converted, I started putting together a list of what Drupal's forum module can and can't do, including with contributed modules. As I've been putting it together, I've been wondering if the list could help Drupal's developers by calling attention to areas that are currently lacking.
This is a pretty big list. I'm writing it not just as a list of things that *I* want, but as a list of things that are common to most forum packages, things that other people might want/expect. Some of them are features, some bugs, some are as simple as changing a feature's name/description to make it more clear. At the current stage, I'm trying to verify that each item on the list is in fact something that can't currently be done with Drupal, either with the core distro or with extra modules. To that end I've been sifting through drupal.org, looking for issues, feature requests, general forum posts, etc. that relate to items on the list, and marking down the URLs for each that I find.
