And just for future reference, a potentially relevant paper on assessing quality of comments in source code:
Steidl, Daniela & Hummel, Benjamin & Jürgens, Elmar. (2013). Quality analysis of source code comments. IEEE International Conference on Program Comprehension. 83-92. 10.1109/ICPC.2013.6613836
I would say that I feel doing something like this is out-of-scope for this effort.
