Congrats - love this, especially joining across old and current data (or any point in time if i understood well?)

I recently stumbled upon the concept of "bitemporal modeling" (ie. rewinding data "as of") - thought it described well this use case.

You understood correctly! That's just one use case, there are many, many more. Some of which we haven't even considered yet, just because the model is that powerful.
