Absolutely.  LLMs tend to work for this even when they cannot parse the
code accurately, which is where other refactoring tools such as
Coccinelle fail.  We shouldn't forget that there is still a significant
barrier, particularly for large code bases such as GCC, but it's about
funding and not about knowledge.  On the other hand, those of us who can
afford decent development machines are still at an advantage anyway.
