I don't know if it's "formal", but I think combining Roslyn analyzers with an LLM and a human in the loop could be game changing. The analyzers can enforce intent over time without any regressions. The LLM can write and modify analyzers. Analyzers can constrain the source code of other analyzers. Hypothetically there is no limit to the # of things that could be encoded this way. I am currently working on a few prototypes in the vicinity of this.
