I discussed how/why the point of this article is very much not to “parse everything” in this followup: https://lexi-lambda.github.io/blog/2020/01/19/no-dynamic-typ... In particular, it articulates precisely why it is fine to use relatively wide types for any input which the program treats opaquely, and it gives an example of how the same techniques can still be useful even in that context.
