You brush over one of the key problems: Pastebin. You don't even need to be able to code. All you need is to pastebin someone else's code and you're done. The mod author even fully admitted that one of the major balancing features of CC is the challenge of writing code. Even assuming this is a valid point, Pastebin completely eliminates it.
Can you disable the crafting of turtles entirely? No turtles, no way, no how, ever? If so, then I would reconsider CC.
I intentionally glossed over pastebin, not because I don't think its a valid concern but I was focusing on the other point. I just had a look through the CC config file and I didn't see an option to disable configs i'm afraid. Maybe its something to suggest to the author. You might know this already but I will mention it anyway, there is a config option that allows you to enable/disable the HTTP api. I am pretty sure that it will also disable the pastebin program if you set it to false.
As a mod pack maker, are you concerned about end users changing your configs to enable a feature that changes the vision* you have behind the pack.
*Sorry for the cheesy word. I couldn't think of a better one.
