One of the biggest issues I see is the overcomplication of minor things. OP's link has examples. It wants to write every piece of code as if it is a user facing API. It will try to triple check every piece of memory that enters a function, even if the function that called it had it hard coded. It's really insane when it decides that due to all the error checking, it should create a helper function just to hold all of the error checking code for something that was spun up with the class default values.
