Everything about language maintenance isn't "just" adding features. There's actual bug fixes and a bunch of other stuff that take a lot of time. Not to mention that Python's standard library is relatively large.
If more people are working on it full time, we'll just get more Walrus Operators. A very hypothetical gain at cost of an increasingly complex core language.
/rant. Those kind of features are going to keep coming anyway, I'm afraid.
It's like someone used to PHP or JS style coercion, doing: 1 + "2", getting a type error and asking "wtf python?".
The walrus operator is obvious, and very handy in many cases.
The capture part of the pattern matching PEP, on the other hand, has been designed shodilly.
