Operators have been translating their service configurations into YANG and are looking how to adapt their service models to proprietary operator models. For them, having standard config models, would make it much more easier to translate their service models and let the vendors worry about translation from standard to proprietary models.

As far I know Arista has their own proprietary schema language (as many other companies have it too), that describes their data model. Arista uses that schema to generate binding to be able to access all objects generated from the data model from python.
If they use their proprietary or use IETF YANG to describe the data model is a decision companies have to make by them self. There is a benefit to have a standardized language that everyone is able to understand.

this is one part I don't understand. Why adding another language would make them less agile?
