Hi CurlingMan,

I really appreciate all the work you do with OSM - closing so many notes is no small contribution to the community.
That said, I'd respectfully ask that you reconsider closing notes like this one. While it's true that unmapped buildings are common, the goal isn't zero notes - it's a complete map. Notes like these serve as reminders for future mappers (including myself when life allows) about areas that need attention.
When I was starting out with OSM, notes were exactly how I discovered what needed improvement. By keeping them open, we're essentially creating a to-do list for the community. Closing a note without addressing the underlying issue removes that signpost for future contributors.

I know you're doing a ton for OSM and I don't mean this as criticism - just wanted to share a different perspective on how these notes add value beyond their open/close count.
