I am curious to learn more about cases that worked for you and those that did not. There are intentionally no recommended use cases so as to not limit what people can do with it but rather learn from the emerging use cases. Unfortunately, I haven't thought through the information gathering strategy, so most of the feedback I heard so far boils down "it didn't work for me" without any other actionable information. There seems to be a common problem of people conflating the idea of capturing (parts of) IR transformation in the IR itself with the limited set of transform ops currently available upstream.
