Sould extract place the sample dims on the left?

Position of dims is not so important in xarray, but when we work convert back to numpy it is.

I was suprised by the behavior of placing the stacked dimensions on the right. Any reason for this?

It sounds like it would also be more likely to involve a copy of the underlying data compared to if it was kept on the left, where samples/chains usually are?

Thanks @ricardoV94, can you do us a favor and give an example of the code now, and what you would have expected it to be, given your observation? The ability to compare and contrast in the issue will help facilitate the conversation and for us to debug.
