Calling an idea problematic is a tell that he's not really concerned by matters like whether it's correct or not.

Web servers and clients, for example, are a case where I've seen bad architecting cause months of damage. An Emacs function hook or advice system, likewise, requires care in terms of when the hook is called, and what the rules for their scoping are. It's a bad software architect that thinks they can just slap callbacks on something.
