No concerns with the definitions defined, although it is unclear to me how they are used if not referenced in API request/response. I assume an enum needs to be updated in a future iteration?

About the referenced,, we use "x-ms-discriminator-value" to extend the "Dataset", and the "Dataset" has already referenced in API request at specification/datafactory/resource-manager/Microsoft.DataFactory/stable/2018-06-01/datafactory.json. So the newly added one can be used in API request. DataFactory always add new connector by this way because we add new connector type in high frequency.
