Disagree strongly.  What is being accomplished is raising the visiblity
of the issue within the language itself. I would argue that the status quo
conspires to underplay the significance of the issues involved - no harm
done to those who already understand them.

One imports copy, like one imports cgi or tokenize. To a beginner, imports
from outside  modules  is strictly special purpose stuff. In my case it was a
long time before much beyond math ,os and sys perhaps, were anything
more than absolute exotica.

As I said, whether I am correct that it would be a significant enhancement
making Python better designed to get beginners aware  of and over some important
humps, is not where my larger doubts are.  Of course realizing a) I could be missing
something  (but I would need convincing) and b) even if I am not., that it would
be a long and - if the past be a guide - probably fruitless effort to try to convince folks there is
significant merit in my position.

My doubts are more as to the other implications that are more technical.  The
shallow/deep copy issue I understand is there and real - but I don't
really understand the issue itself.  I will do some homework.
