So, you don't like the extra parentheses with print. But you don't mind the
parentheses in sys.stderr.write (16 chars, versus five for print) or having to
manually concatenate the strings and manually add a newline at the end. Because
apparently using print and sys.stderr.write is simpler than print with parens.

What simplicity? It adds complexity, not simplicity: do you need brackets or
not? Why is print special? When do I use print and when do I use
sys.stdout.write? Decisions decisions.
print(len mylist, "items in the list")

Oh yes, that's an excellent idea: make it even harder for beginners to learn
when they do and don't need parentheses :-(

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure
enough, things got worse.
