By reakinator:

The point of the macros was to spell out what the cryptic error codes were telling us, instead of having to convert it from hex or result to googling the error code. With the macros, you get a clearly labeled string that tells you what the error is (well that's the idea anyway).

Also, they are done, so it is no more effort to leave them in there. I think renaming them to fully reflect their actions upon failure is a good idea, though.
