Hi Mormegil,

I wonder why you replaced subject:wikidata with memorial:subject:wikidata? subject:wikidata has 57927 uses, memorial:subject:wikidata only 47 and its wiki documentation page is proposed for deletion: https://wiki.openstreetmap.org/wiki/Key%3Amemorial%3Asubject%3Awikidata

why did you remove historic=memorial+memorial=plaque here?

https://www.openstreetmap.org/node/11267614870/history
https://www.openstreetmap.org/node/11371591552/history
here you just removed the wiki tags without replacing them
