I would expect wine shops to be covered by shop=alcohol.
The tag docs for shop=alcohol were somewhat muddled for a long time, by the older tag shop=beverages, which created a lingering confusing around "government licensed" in the definition. Hopefully its getting clearer now. ...but adding this shop=wine page feels like a step backwards.
It's a tag which is in use though, so from that point of view it's not a bad idea, but I think we should point people clearly at shop=alcohol, and this should de-listed from Map Features.
- I don't really have a strong opinion. I created this page because the tag was in use and I wanted to document it, not necessarily because I agree with its use.
- I think that in England, a shop like Majestic Wine (shop=wine) is quite different from a typical off-license (shop=alcohol), so I can understand why people tag them differently. On the other hand, merging both tags might make simplify things.
