Frankly I think this entire discussion suffers from trying to cookie-cutter force the British classification upon the Polish system, coupled with the fact that Poland's administrative division and village styles both suffer from having developed from three different 19th century systems. The second aspect is that linear villages are extremely common in Poland, especially the further south you get, compared to the British Isles (I say this having lived long enough in Ireland), but you appear to dismiss them as possibly being villages. In other areas of Poland the hamlet tag is used for tagging names of parts of continuous villages and the distinction of a hamlet being part of a village is clear there – I hope you're aware of this. (Lastly I think the OSM Wiki is written horribly: there is no clear continuity from article to article as to what delimits one from the other.)
