I would like to continue to traffic in LangAS, if for no other reason than that it promotes better habits within CodeGen. Otherwise, I think we will end up with a lot of code that immediately lowers address spaces, and that will make it very difficult to treat address spaces as a frontend abstraction if we ever do have a need for that, which I continue to believe is a likely future development.
