Our language centers evolved to build our "natural" languages and our "natural" languages evolved to take the best (most?) use of our language centers. Whether or not it is ambiguity or simplified context or some other "complexity mechanism", if you agree with the Chomsky hierarchy that our "formal" languages are pure subsets of our "natural" languages, then that alone would imply we use only a smaller subset of our language centers when working in "formal" languages.
Though yeah, that does feel awfully reductive as an argument, and leans on a lot of assumptions in Chomsky's theories. I know that there are axes where "formal" languages feel more orthogonal to "natural" languages than "pure subsets". Some parts of "formal" languages to me feel a lot more visual like poetry than linguistic in the same way as prose.
