Point taken, but we'll see. Miniaturization comes at a price. No one
ever replaced panel-mounted phone jacks as frequently as we do
circuit-board mounted miniatures today. Nor did we replace mic cords
and plugs (same with telephones) as often as we have to today.
My overall thesis on dependability still stands, I think, as witness the
vintage crowd and their still-going-strong at fifty-plus years gear.

Hi, Kent!
Kindly take one more look at that warning. It is referring to the
internal RF Power Level control (R4 trimmer pot).
The RF Gain pot topside is expected to see much more use and was
selected because it will last a long time.
Merry Christmas!

However, by comparison, during assembly of a KX1 I did note the
warning in the manual about not turning the RF gain control too
frequently because that pot "has a life expectancy of 200 rotations."
Hmmmmmm. I know I've rotated the RF gain (and also the AF gain) on
the R4-B a lot more than 200 revolutions over 36 years and have yet
to need even a squirt of De-Oxit on either one of those pots.
