should we have separate objects for https://www.openstreetmap.org/node/5703209919/history and https://www.openstreetmap.org/relation/6701391 

?

Also, all this official_names are not actually official names.

Unless relevant local authority of UK joined onto this?

I propose to retag them as loc_name:*
