The fundamental problem with fixing optlink is there is essentially no test suite.

Wholesale refactoring "just because" or for "cleanup" are out of the question. Wholesale reformatting is also out of the question.
The solution there is to write a comprehensive test suite. Then it can be refactored. I'm not saying it's an easy solution, it's probably a major pain, but that's what it is.
