(Not) from who? I think in general Pythonistas complain that the
"zero-character identifiers" harm readability. Someone already said this
in this thread:

In the rare cases that I am writing Java or C++ these days, I absolutely
use "this" explicitly despite the lack of a requirement to do so. It's
simply more readable in the long-term.

Feel free to write code like this for yourself. I don't see anyone
"approving" any sort of "shorthand form" ever. The only official stance
on coding conventions is intended to guide the writing of code for the
stdlib. I find it very unlikely anyone would accept "S" in place of
"self" within the stdlib. Furthermore, I think the likelihood of having
another developer working with your code will sharply go down if you
stray from the guidelines for the stdlib. But to paraphrase what someone
else in this thread already said: what you do in private is your business.
P.S. Top-posting is inappropriate for this list and makes it more
difficult to follow long discussions (like this one).
