I think this post overhypes the issue. So many writes we do just aren’t that important (e.g. logs, cli config, blah), Close fails rarely, and it’s pretty standard for casually developed application software to misbehave once the disk is full or breaking.

This is a classic safety / performance trade off that was properly selected in favor of performance.

The defer Close() is still quite useful as a way to avoid fd leaks.
