Is your feature request related to a problem? Please describe.

Exported package doesn't make much sense. In group it's used to describe a dependency for the group module. So it can be in the group module package itself.
Moreover, it doesn't export any useful type outside

Using exported, as a package name is not idiomatic, and it's blizzard..

Describe the solution you'd like

The obstacle in the simulator is not in map.

Possible solution:
Add obstacle to navigation map so it shows up in the static costmap.
