Yeah; it's all a balance between simplicity vs risk of confusion. From
using, teaching, and witnessing people teach SageMath, there are some
contexts where you (or more likely your teacher!) know what you are
doing, there is no risk of confusion, and simplicity primes. Most of
the time we don't want it though. So +1 as well on automatic_names as
an option not set by default. Also +1 on the message when a variable
is created.

Finally, I could suggest to write it as:

        %automatic_names

to highlight that this is a magic command that alters the behavior of
the interpreter.

Cheers,
