Hi, HN. A few days ago, I discovered that `del list[index]` never reallocates the underlying array (anyone familiar with data structures knows what I mean) starting with 3.13.0a5. I posted an issue, and then, as requested by a member of the Python organization, I also submitted a PR.
However, to my great surprise, they initially tried to dismiss the issue by claiming "it is not a bug", then "the fix is too slow" (the comparison with `list.pop(index)` was completely ignored), and later "it is specific to free threading" (it is not). In a new PR from another Python team member, they propose not shrinking small lists for every operation at all.
I invite you to assess the situation for yourselves and decide whether this is really the right approach.
