That would be a monumental task! I'd guess that every block in Fell's Point/Canton has a few of these... I think they're called sally ports, but barrier=sally_port isn't accurate. Also, I think they're mostly private ways, so I'm not sure the value of adding them—other than extreme micromapping—before other features like updated POIs or sidewalks.

That said, I love micromapping.
