Some will ... but more than half of all computers sold today already
are not desktops (and at Apple, over 75% IIRC). As such, the
consumers are voting with their wallets for what's important to
them ... and it isn't for gobs of inside-the-box expandability.

Except that the attempted point fails because there's not many
different ("Better") models of PCIe cards sold for the Mac Pro to put
into these empty internal PCIe slots. Here's a full list:

graphics-cards-dvi-dual-link-mini-displayport.html>
The ATI Radeon HD 5770 and 5870 are the Apple OEM choices, and per the
above (and barring DIY flashing of ROMs), the 3rd party aftermarket
is:
NVIDIA Quadro FX 4800
NVIDIA Quadro 4000
AMD Sapphire Radeon HD 7950
PNY NVIDIA Quadro K5000
EVGA GeForce GTX 680 Mac Edition
Haven't bothered to look at the rest, but the K5000 calls for a 16x
slot, so it probably can be expected to saturate a TBv2 connection -
but at $1800 for one card, this should pretty much be expected.

That claim would be relevant if these Adobe Mac software products
materially leveraged the GPUs in the video cards for enhancing
performance. Granted, there's some GPU-aware filters now (finally) in
Mac CS6 for Photoshop, but per the Adobe support pages I checked,
there's no OpenGL acceleration in Lightroom at all.
For example,
"Lightroom requires a video card that can run the monitor at its
native resolution. Built-in, default cards that ship with most desktop
or laptop systems typically suffice for Lightroom."

FYI, here's the Photoshop page - good luck figuring out when/where
they're talking about Mac vs Windows:

...as well as relevant performance benchmarks for how much of a
difference a better video card might actually make, even if your
workflow involved the specific individual tools (filters) that Adobe
has improved...yes, this last part is an important caveat because the
modular structure that Adobe has used for Photoshop means that the
enhancement doesn't change performance across the board, but only for
the individual filter (subroutine) which got GPU awareness added.
Which is precisely why I said "materially", above.
