There are many long-term users of Python who participate in PEP discussion who argue for beginners[0], often because they professionally are teaching Python.

There are also loads of people basically defaulting to "no" on new features, because they understand that there is a cost of supporting things. I will often disagree about the evaluation of that cost, but it's hard to say there is no cost.

Nobody wants a system that is unusable, slow, hard to implement for, or hard to understand. People sometimes just have different weights on each of these properties. And some people are in a very awkward position of overestimating costs due to overestimating implementation effort. So you end up in discussions like "this is hard to understand!" "No it isn't!"

Hard to move beyond, but the existence of these kinds of conversations serve, in a way, as proof that people aren't jumping on every new feature. Python is still a language that is conservative in what it adds.

This should actually inspire more confidence in people that features added to Python are _useful_, because there are many people who are defaulting to not adding new features. Recent additions to Python speeding up is more an indicator of the process improving and identifying the good stuff rather than a lowering of the bar.

[0]: I often think that these discussions often get fairly intense. Understandability is definitely a core Python value, but I Think sometimes discussions confuse "understandability" with "amount of things in the system". You don't have to fully understand pervasive hashing to understand Python's pervasive value equality semantics! A complex system is needed to support a simple one!
