I don't even think it should be used with Devs. For one, a good dev should know how to build queries, otherwise he/she is missing a good foundation, in which case shouldn't be working with the db. Just my personal take though
I know how to write assembly, but I still develop most of my software in Python. If this makes hairy queries more readable, I can see the use case, even if it doesn't replace SQL itself or the need to know it.
