We removed shop because of the complexity of configuring Shop-Warehouse-Location.

The former Sales Shop object has been removed in order to simplify the Sales process. The pricelist and destination warehouse can now be selected directly on the Sales order, when relevant.

Selecting a warehouse in the sale order is logic. (instead of a shop). If you used shop for reporting purpose, you will use sales team in v8 that better serve this need.

What you used to call "Shop" has been renamed to "Warehouse" and it can be found in the "Other Information" tab.
