Adding this capability to a design that lacks it is not nearly as
simple as you seem to think. And the DSLR's are built off a platform
that lacked this capability to begin with (The *ist, which shares most
of its mechanicsw ith teh DSLR's, although the frames are
substantially different).
Where the hell do you get that? Have you even held an *ist and *ist-D
at the same time. The two cameras are very different, a fact that was
pointed out by a number of reviewers when they were both released.

Hardware is certainly harder to integrate. With hardware you have the
software integration issues still (Since you've got to add support to
the firmware for the hardware you've added) plus you need to find
space for the hardware, ensure it doesn't interfere with any other
hardware and ensure it is electrically compatible with the hardware,
and this is something that essentially needs to be done with any fresh
design (Even if the interface specs are identical, like the K mount).
I'll pretty much guarantee that the implementation of the aperture
coupling is different(Although similar) from model-line to model-line.
You can't just drop the hardware from a MZ-6 into an *ist D and call
it a day.
Software, especially when it's simply piggybacking on already existent
functionality like the Green-Button solution, is much easier to add as
long as you have sufficient storage and CPU power. The green-button
fix is likely a module or two drawing functions from the DoF code and
the pre-existing Green-button code to make it stop-down meter then set
Tv (the latter portion of the code already existed as part of the
Green Button functionality in M mode with fully-supported lenses)
And testing is a whole othe rball of wax.

While the lenses do exist, the number of owners looking to buy into
Digital or modern film are a fairly small fraction of the current
market. Barely worth supporting, and not worth the extra engineering
required to integrate the extra functionality into the design
(Hardware is always harder to integrate than firmware, hence the
firmware fix).
