Selective revert of splitting river from boundaries, in changeset/46706281. All newly added residential objects preserved.

Full revert in changeset/46695208, landuse restored and overlap fixed in changeset/46695608.

This CS, beside adding lots of nice houses, deletes 2 landuses and a school and redraws them, nearly identical. It appears to be an attempt to unglue adjacent landuses.
So first, this in not necessary as these areas are attached to each other, second there would be the 'unglue' function in JOSM (G key), or alt-J to release a glued node from a way, so no need to delete objects.
Restored old objects and deleted new ones in changeset/46693752.

Hi gaz3434, you have accidentially added building=yes and amenity=place_of_worship to the whole church ground. That should be used on the church itself, only (way/434336493).
I have meanwhile refined the grounds and drew the church building. You can use landuse=religious for the grounds.

Full revert in changeset/46692924 for incorrectly separating roads+waterways serving as border member; restoring useful additions in 46693197, refinements in 46693752.

Victor, when reverting changeset/46496897 with the boundary splitting, I had to include your CS here in the revert.
I attempted to restore useful stuff from both CSs, you might doublecheck.
It would be a good idea to do repairs and own additions in separate CSs, though.

I was in PM discussions with the user, as this has been commented in other similar cases as well. I think this is understood now, and I am repairing these issues backwards over the next few days.

@VictorIE: those will be fixed automatically when I revert the incorrect boundary line separations.

fine

Selective revert of the separation of waterways from border lines (changeset/46688164).
The roundabout way/204728237 was not visible neither in bing nor Bing, exceptional source:geometry set according to previous changeset comments and GPS evidence (changeset/46688307).
Selective revert of the separation of Coa Road from border lines, which caused cycle routes going over border lines instead of roads (changeset/46688805).

Fully agree with hsimpson and kreuzschnabel on my practical experience using OsmAnd, and find the calculation by 'its so funny' rather theoretical.
The satnav device is just part of the information I process as a driver.

Hallo webpassenger, sehr nett. Allerdings stehen einige der Eimer auf der Strasse. Kannst du in deinem JOSM den DOP2016-Layer aus dem Geoportal einbinden, und mit deinen GPS-Daten vergleichen? osm.wiki/Geoportal_Berlin

This CS deleted school way/255709094, just to redraw the nearly identical campus in way/478058571. Same with boat house way/255709093 and way/478058570. Original versions restored in changeset/46654702. School campus is sharing the river boundary, that is fine. Boathouse was sharing a node, fixed.
A river defining a border was drawn in parallel. New way removed and tagging restored in changeset/46654924.
For resolving a forest multipolygon into a simple, two original outer members were deleted, instead of using the larger one to extend it to the full outline. Not restored.

Haven't checked the node (which?) yet, however I'd also prefer to have the split at the physical separation and not the legal separation.
As the wiki talk page shows, that seems to be controversial, though.

On way/310656818 you removed the 'wall' tag a local mapper had used. bing clearly shows a structure here, and dry stone walls are quite typical in Ireland.
