This makes no sense at all. If the so called no-code techs can't do code
now, how would giving them access to code only portion of the bands help
them learn code? If they want to listen to code, they can do that now
without a license. There are code portions of the 2 meter and 6 meter
bands that they have access to now, but I'll bet none of them go there
to practice code!

One feature of letting them use HF code bands is propagation.
They would more likely be able to find someone else to QSL
with somewhere in the country vs only in their county. And
as hams already they should know the protocols about listening
first to see if the freq is in use at the time or not, etc.
