The complexity is in making contradictory elements of a character inhabit the same body and provide the dynamics that drive the comedy - in such a way that you can do it time and time again. Think of Frasier. Everybody is complex in real life, pretty much everybody anyway. In sitcom the most important questions to ask is what does my Character want and what stops him from getting it? The best anser to the latter usually is the character himself, and to do that repeatedly, and believably, you have to make that character complex to some degree. What does Mainwaring want - he wants to be respected but on a deeper more complex level he wants to be loved. Now if that isn't in him as a character you don't get the depth that is there and can be explored in episodes like the one where his twin brother turns up. A simple analysis would be that he is an arrogant character who gets his pomposity pricked, but it's not that simple at all.
You're picking one of the great sitcom characters there. From one of the great sitcoms. There are plenty of other examples from similarly great sitcoms written by writers who know their onions.
Generally speaking, I don't think there's much complexity in most sitcom characters.
