Yup. At least it's self-contained and easy to step through and modify if something breaks or needs to be changed.

And, a my previous PM would point out, even the copy-pasting and verifying no mistakes were made was a solution that took a fraction of the time a modern "clean" approach would. She had a point; as much as I'm against writing this simple code in the general case, plenty of devs tend to err towards overcomplicating solutions when given a chance.

I mean, the modern, proper, Clean Code™ solution would have this split into multiple files (not counting tests), and across two or three abstraction levels. I've seen this happen enough that I can tell I'd much prefer working with code like this capabilities parser (and hell, it can be beaten into near-perfection in an hour or three).
