I tried to make that point 2 years ago:

The article was unfinished and there is a follow up a few comments later.

Can we pre-order the KDTT yet?

Hello All, Just a thoughtbut how about a external power supply for the
KPA-500 ? It would leave plenty of room for a built In antenna tuner ?

I agree, I don't mind an under the counter supply.

I think an internal power supply for the KPA500 with an external ATU from
Elecraft makes a lot more sense.
I like the remote-ATU idea, especially, if it incorporates an auto-tune
feature as well as a means to integrate switched antenna ports. A 500W
auto-tuner with say...six SO-239 ports

I may have missed it, but I would like to know more about the KPA500's T/R
function -- namely, is it 100% electronic with PIN diode switching? Or, are
frame and/or vacuum relays used at the amp input and output? A silent,
PIN-diode switched amp
Would moving the Power Supply out of the KPA500 enclosure leave room for a
2nd 500 RF deck inside the K3-sized enclosure? Could two 500 Power supplies
fit in another K3-sized enclosure?

Hello
It's probably possible to build a KW power supply into a K3 enclosure, but a
power supply of that output would absolutely require 220VAC lines, which I
believe is one of the reasons Elecraft focused on the 500 watt amplifier size.
500 watts is about the limit for running an amplifier from 110
probably not enough room for the FANS :)
