I can't read Polish and I am having some trouble following along.

Could we recap.
- We have some parcel boundaries from the Polish forest service.
- Some of them have been imported as a landuse=forest, which was known
ahead of time to only be 80% accurate as far as matching where the
forest actually is.
- Mappers are correcting the landuse=forest to match the tree's on the imagery.
- Mappers involved in the import would prefer that they not be edited,
since they are really parcel boundaries.
- These parcels are broken up into squares where each square has some
kind of name/address? This is also a kind of address import too.

This seems like a tricky import, If I am following along, more work
should be done on the tagging perhaps doing more processing of the
geometry to match OSM's data model.
