Though a joke, it does touch on something I've seen happen multiple times. A program goes from having human readable config files, to having a little built-in scripting language. An app that I use has built-in editors for 5 different languages, because each language evolved within a different section of the software. One of the languages is a crude version of BASIC. Plus there are instructions for interacting with the software via two different inter-process communication architectures: DDE and something else. Naturally it brings the risk of second-system effect, but were this program to be written from scratch today, they'd probably just choose a scripting language from among the many interesting FOSS offerings, and use it across the board.
