Yes - I have seen at some jobs what a horror "configuration files" can be if you let people add programmability into them. Many years ago I worked at a job that made an XML tag-based language that was turing complete with the intent of it making their configuration "smarter". It ended up making the entire project much more difficult to debug, trace through, and even understand at all.
