some kind of waterway is here

source:maxgcweight = PL:sign_B-18?

B-18 to chyba jest znak dotyczący masy rzeczywistej? nie maksymalnej masy dopuszczalnej?

Więc tu chyba zwyczajne maxweight (i source:maxweight) powinno być?

node/356696563

this imported place=island appears to not exist (anymore?)

I guess that it should be deleted?

way/615113370/history has shop = home_improvement

Is it shop=doityourself ? If not, how it differs from shop=doityourself? See shop=doityourself

way/434881505/history has amenity = storage

amenity=storage ? Is it simply a shop=storage_rental? See shop=storage_rental Or is it selling boxes/packaging? Or for storing luggage?

node/2613439338/history

what barrier=water means here?

way/1022877810/history this name ("Plage" on natural=beach) is a description and can be removed, right?

way/97784490/history has landform = beach

Is there some reason for using landform=beach? Rather than normal natural=beach

way/1271471520/history has tracktype = 2

Maybe it was supposed to be tracktype=grade2 ? See osm.wiki/Key%3Atracktype

way/68894847/history has shop = education

shop=education ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from shop=* or osm.wiki/Category:Tag_descriptions_for_key_%22shop%22 fitting? Maybe new value needs to be invented? Maybe this data is wrong and there is no shop here? Maybe it is not a shop but something else?
