SDoc is an abstraction for generated formatted text including the assembly the compiler generates. The problem was not that the code generator was generating extra output, but that the text-formatting functionality it used was doing extra bookkeeping that made sense for human-readable text but was not necessary for machine-readable assembly.

Using the same abstraction for both seems a bit silly at first, but it helped the codebase stay more consistent and was already pretty well-optimized. The changes in the article optimized it further by splitting out some of the more expensive functionality while keeping the same general engineering advantages.
