Credit Limit check in pipeline for currency resource is not supported

The pipeline does not do credit-limit checking for currency resources as in the current pipeline integration design, currency resources are not

synchronized to the pipeline -

However all the non currency resources are synced with Pipeline for discounting, real-time rating like cycle forward, purchase fee, adjustments etc.

Can not the same be applied for currency resources. How can credit limit check can happen in delayed usage for currency resource? 

Solutions such as maintaining a dummy non-currency along with current currency resource in all configurations and rating is not practical and I am not looking for a solution on balance monitoring.

Looking forward to your kind advice.
