TBF from what I picked up from their occasional mentions of the topic, under the hood CoC was something of a case study in how scope and feature creep far past what the code was originally written for result in a barely-functioning Frankenstein's monster of ad-hoc kludge upon another that's a giant pain in the ass to actually work with. No wonder they just dropped it eventually; and TiTS was from the start designed pretty specifically to allow for considerable expansion without that kind of ungodly mess, lessons learned.
