In general this reflects map data which could be improved, typically by replacing nodes through with area polygons. This is not always possible when particular areas have a well-defined name, but the boundaries are somewhat fuzzy (one reason why OSM is very light in names of mountain ranges, valleys etc.).
One last point, as with Wikipedia, it’s always best to assume good intent on the part of other contributors.
Those are generally hamlets, refugee camps etc. not proper regions.
We could use the actual districts and prefectures of Israel (מחוזות ונפות). Is there a map from the ministry of the interior, like the one you scanned for the municipalities?
