I suspect this restriction is so the connections are easy to locate
if there is a fire. But, as a volunteer fireman, I can assure you
that during the fighting of a fire we are not going to be looking
for a junction box as one of the first things we do is shut the main
power. I think this is just another "feelgood" clause inserted by
some desk jockey.

The code requires junction boxes for splices to prevent fires from
occurring due to faulty connections, and requires them to be
accessible, so electricians can make repairs. OTOH, people who put
out fires, tend to use axes, not screwdrivers to do their job


Bingo!

PS: And just to show you how brilliant that desk jockey that included
that in the code is, short two 12 guage wires together in one of those
blue plastic boxes and see how long it takes to obliterate it.

I'm sure the desk jockey included requirements for circuit breakers that
would trip before the box got that hot.

If somebody piled confetti on a faulty connection carrying 20 amps, it
could reach kindling temperature. The box is intended to let that heat
dissipate.
