The idea that str.format produced simpler or more readable code than f-strings is contrary to the experience of most Python users I know. Similarly, the contortions we have to go through in order to work around the lack of assignment expressions are anything but readable.

I do agree that Python is moving further and further away from the only-one-way-to-do-it ethos, but on the other hand, Python has always emphasized practicality over principles.
