I'd call them all contrivances, for a start. This feeds into my feeling that the domain system has always been something to bend, break, and work around rather than a mechanic that was enjoyable by any means. Your response there also doesn't address my distaste for how they force you to lump added portfolios in with the same general theme instead of truly branching out.

Why shouldn't a newly created god simply be allowed to have 1-3 portfolios that could be closely related, unrelated, or even in opposition with one another?

No reason at all, tbh. 

I've just never seen it as a big deal. Look at Jvan- she has a vaguely beauty-related ideology, and then... almost exclusively flesh powers. Her current additions are space travel and mathematics, and her future ones will be psychokinesis, unarmed combat, and memetics. So nothing she does bar maths and memetics really have anything to do with her domain, and even then it's tangential. Beauty's just an overall theme for her personality.

ed: Over time I've come to think of ports as predominantly a mechanic that lets you specify anything your god doesn't need Might for.
