I don't think things would be very different if Guido were still BDFL. He's second-author of the t-strings PEP, and has been an author of most other major PEPs in recent releases (including the walrus operator, PEG parser, and pattern matching).
It's so fascinating to see so many people, when faced with a simple and useful programming language feature, get all up in arms about how it's the end of the world for that language.
I honestly feel like a lot of people just seem bored and looking for stuff to be mad about.
