In versions prior to 14, Routings were defined on the BOM level. Work Centers and Operations were set up under Configuration. Various combinations of the Work Centers/Operations could form a defined Routing that could then be assigned to a BOM. 

With version 14, it appears the defined Routing functionality has gone away. Instead, each Routing is effectively created on the BOM level. I'm assuming Odoo got rid of the standardized routing function in order to achieve the flexibility showcased in version 14. This new flexibility lets you modify almost anything on the BOM and MO at any stage. Previously you defined the standard Work Centers and Operations through Configuration and pulled them through to the BOM via Routings. Now Routings are gone and you effectively push the Work Centers and Operations from the BOM backwards to the list in Configuration. Since every Operation and Work Order can be specific to a BOM, I don't understand the purpose of even having a "standard" list under Configuration.

While manufacturers probably need flexibility, it would seem that many (or even most) would have standardized routes in their production processes. Depending on the BOM, they could select the appropriate route. Many manufacturers might only have one route.

In our case, every MO is unique and built only once. Every BOM is unique in terms of materials and built only once. However, the Work centers/Operations (Routings or manufacturing steps) are the same on every production run.

Is there anyway we can have the standardized Routings functionality without staying with version 13 or will this require customization?
