Jinwon, Thank you for the information. It seems your memory is much better than mine. During the refactoring effort we have moved away from the concept of 'model' vs. 'obs' and we are instead calling a Dataset, well a Dataset (regardless of it's source). This has enabled us to run ensembles and to compare models to models or even obs to obs without much issue.
Given the experience of users providing regridding options, I think we have a workable solution.
