way/289909900/history has shop = 焼肉

shop=焼肉 ? 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?

way/221148845/history has maxspeed:source = sign

is it intentionally used instead of source:maxspeed=sign ? See osm.wiki/Tag%3Asource%3Amaxspeed%3Dsign

maxspeed:type is also sometimes used as a key for such data, see maxspeed:type=*

way/635879865/history has source:maxspeed = practical

Can you explain meaning of source:maxspeed=practical ?

Is it mistagged maxspeed:practical= - realistic estimate of possible speed, lower than legal speed limit? See maxspeed:practical=*

way/552945057

Is it really named Jardinera like several similar tiny ones around?

is it maybe flowerbed/shrubbery rather than a garden?

way/331588367/history has id = 12

What is the meaning of this unusual key? Is this tag needed?
Or maybe can it be expressed in a more typical way that would be easier to understand?
Or maybe this key can and should be documented as useful tagging schema?maybe ref=* would fit?

node/2862834811/history

wait - is it actually a pawn shop? Or place where pawn shop sells various products, making it closer to shop=variety_store ?

can you take a loan here or only buy used stuff?

way/416176771/history has shop = cigars

Why not shop=tobacco (with tobacco=cigars), see shop=tobacco ?

Do we really need both shop=tobacco and shop=cigars as top level values? Having separate top level values for minor variations makes using OSM data harder.

If shop=cigars should exist, documenting it at shop=cigarettes would be useful (see osm.wiki/Creating_a_page_describing_key_or_value )
