No? Its about errgroup ctx being automatically cancelled once the group is done (in success or err). It kinda makes sense, and its documented. I understand how it can be surprising, but if you think about it for a second, it makes sense. The context created is meant to manage the lifecycle of the errgroup. Once the group is done, the ctx is done.

It's only about context _returned by errgroup_ being cancelled, you shouldn't be overwriting it in the way in which it was used by an article, which is really hard to spot due to variable shadowing.

There is no shadowing.

It's also harder to spot that this is a bad pattern because it's exactly what the package examples currently do.
