I suspect it's similar to why we don't use Lua, Python, or whatever language is considered easy and quick to learn and write as a shell language. There are specialized cases where it's much, much faster to write commands in a custom language (even if it has to be a "proper" (e.g., Turing complete) language and not just some tags like markdown). From my limited use of AHKv1 a decade ago, I would suspect that AHK is such a case. You can get a long way with operator overloading, but having seen students who had decent C++ knowledge use CPLEX, I'm not sure it makes things any less confusing.
