I believe that this is a necessary evil.  I don’t think that we have a single back end that uses all of the target-agnostic codegen features, or hits all of the important corner cases of back-end development, and so a good document would necessarily cover multiple cases.

That said, I’m not sure that AVR is sufficiently different from SPARC that it makes a good example here.
