Overall reasoning
- tracking "in-progress" in multiple places is hard and the fewer places we do it the better. I've seen in-progress tracked well in team-specific "sprint" or "kanban" boards instead.
- Categorizing tasks by type...
- makes it easy to see where a lot of tech debt lives (or where processes/tooling should be improved, at least)
- helps new comers to get involved
- encourages more active triaging into those categories (easier to do and more reward than just making the huge backlog column even huger)
- and, it more manageable than a single big "backlog" (and to-triage) column
