There is nothing non-compliant about a 1920 watt appliance cord with a

There is if it is not "listed" with the cord.
In most cases that means "supplied with" the cord.

No that just means they submitted that model for testing and it passed
with a cord. As long as that testing exists you can add a cord to that
model in the field. It happens all the time with disposals and dish
washers. Theoretically you need the "kit" from the manufacturer but if
that was enforced, selling plugs would be illegal.
Nothing is technically "listed" if you change the plug.


I stand behind my statement that in "most" cases something "listed"
for plug and cord connection comes "with" the cord.

Didn't say "always" comes with the cord.

Electric dryers pretty much never come with the cord.
I dont think you can buy one in Canada without the cord - which
virtually always comes attached - and by Canadian code cannot be hard
wired.
Same with a freestanding range.

How do they deal with the 3 wire vs 4 wire receptacle?
They are "supposed to be" replaced and rewired.
However in a house built prior to 2000 (3 wire) it is slill legal to
replace the 4 wire cord with a 3 wire.

Another (relatively common) "fix" that has been done a lot is
replacing the 3 wire outlet with a 4 wire outlet with either the
neutal and safety tied together (put a label on it saying "no safety
ground" or (when wired with a cable with 3 insulated conductors)
putting the "ground" wire to neutral and adding a "safety ground" to a
water pipe.

Not code compliant but no worse than the original 3 wire setup,
which is "grandfathered" and also not "code compliant"

It is worse, because now you have people apparently coming up with their
own "fixes" that are not defined by code, rather than just allow the
use of a 3 wire cord if you have an existing 3 wire receptacle.
