The fuzzer found the bug before any humans did, so there is a mismatch of developers who could find this bug and those who did (without an LLM-coded fuzzer).
The value of the fuzzer continues long after it found this one bug.
It's worth nothing that in the bug discussion thread, the bug fix author pointed out that it's not easy to set up the config then call the functions in the right order. Your comment assumes that the reader has enough context to read the code and build the finite state automata in their mind. The bug fix reporter's comments suggest that you are assuming things which you shouldn't assume.
