[Tagging] shop=ice_cream vs amenity=ice_cream and OSM Wiki vs tagging

[Markus]

Strangely enough, the page

https://wiki.openstreetmap.org/wiki/Tag:shop%3Dice_cream

says that shop=ice_cream is "for places selling ice cream to take
home", but shows an image of an ice cream parlour.

Are there really shops that only or mainly sell packaged ice cream for
taking home?

Otherwise, it seems to make sense to deprecate shop=ice_cream in
favour of the more used amenity=ice_cream.
