[Elecraft] Alternatives to PowerPoles?

[George Victor]

"While demonstrating two early K3s at the Lebanon Hamfest last
October, TWICE I tripped on the power cords behind the table.  TWICE,
I said "oh s_ _ _t!"  TWICE I said,  "I'll never do that again."
TWICE, I thanked God for telling Elecraft to use APPs.  TWICE, I was
damn glad they weren't locked together.
K9ZTV"

Was the purpose of this post to tell the group that APP's have a
safety feature, OR,  to inform the group that Elecraft is using APP's
because of K9ZTV?
