It is simpler, more productive and less error-prone for Mesa-like libraries than trying to optimize critical C code&data structures by hand. It is impossible to improve Mesa performance to a next-generation level without refusing some hand-written code. The human brain is incapable of handling so many states. If you don't try it you will never know how far it can go in terms of optimizing Mesa.
