I wouldn't object to having both of those, either, but I accept that ALL designs are compromises, in one way or another, whether we're talking about cars, planes, computers, electronics, etc. Nothing happens for free; one thing always displaces or alters something else somewhere.
There is no such thing as a perfect car, no matter how much we all want one to exist; and there isn't one single vehicle, regardless of cost or configuration, that does everything well. Putting 60/40 and the armrest/pass-through together would be neat (and I agree, entirely feasible), but it would come at the expense of added complexity, possibly reduced structural rigidity, added weight, increased cost, and maybe even ... more rattles!
I'm happy with my Accord, just as it is, especially for how much I paid for it. If I need a vehicle to do something the Accord can't do, then I'll find another vehicle that can. I can live with small quirks, because I appreciate how great the rest of the package really is.
