Good answers. Thanks! I'm still learning a lot of the ghc code base, so I may have a few other questions like this as I try to familiarize with ghc code.
Is the dev list an ok forum for these sorts of questions?

Well, it means that GHC can be used to compile hand-written asm, and it
also means that you can do "ghc -S". Also, there's been no reason to
change it.
