[Tagging] Confectionery shops

[Matthijs Melissen]

Dear all,

Currently, we have the following confectionery related tags:

* shop=confectionery (12045 instances)
* shop=chocolate (730 instances)
* shop=pastry (708 instances)

How should we tag a shop selling cakes? A shops selling croissants and
cinnamon rolls? A shop focussed on chocolate, but also selling other
types of confectionery marketed towards adults?

Should we preserve the shop=chocolate and shop=pastry tags, or should
we make them subtags of shop=confectionery (or shop=bakery)?

Thank you in advance for your input!
