Ok, I can see how that can be confusing.  In any case, I think I've
explained it enough times already in other places.

Yup.  Basically, what it comes down to for me is that cameras like the
Z1-p give me a choice of whether to select the aperture from the body or
the lens.  Pentax didn't compromise the body by adding another button or
dial, but just took advantage of an existing one.  I think that the
advantages (allowing lens support and/or manual focus with your left hand)
outweigh any potential (but I think nonexistent) structural disadvantages.
There are certainly no signficant ease-of-use disadvantages, as you can
use one method exclusively if you want and never have to switch over.

The Z1-p was discontinued for a variety of reasons.  If we're
talking about "for a good reason," Canons and Nikons are popular for a
good reason, as well, and they allow aperture selection via the body.  How
many users is Pentax willing to lose if they refuse to at least give users
the option of using the body to set aperture by forcing them to use the
aperture ring?
