Assignment expressions are also found in languages like C#, and have proven to be of great practical value.

f-strings was another Python 3 idea that was pre-dated by an implementation in C# [1] ($-interpolation) and it was a popular idea in that language too.

I don't want to proffer an opinion on PEP 572 since I haven't followed the discussions, but these things have been "bench-tested" in other languages and not been found wanting, so I do wonder a little bit about the true cause of the controversy.

Yes, I don't really understand the controversy either. I work with Python a lot in my day job, and I am quite frustrated with how slowly the language moves. For a long time, it seemed like the reason was the Python 2-3 switch, but now we don't have that excuse, and things are still slow. Every little decision seems to get immobilised at the PEP stage.
