Yeah.. The users for this feature are going to be people who seriously care about perf. They will certainly want to fix the misconfiguration, and not just run in whatever slow path.

Silently taking a fallback path just makes the problem harder to diagnose.

This would be a good choice for a simple high-level API that targets a wide audience, where people might not want to be bothered with any low-level details, perhaps.

Is it ? This feature would be used by every databases, which would stop doing double writes with their WAL

I cannot understand how "brick the system" is a good solution

Slowing down and pushing an error on dmesg seems quite sane to me: users would have the information, and the performance would be .. what we have today (or a bit better, perhaps ?)
