That's a special case. It's fine but they should explicitely configure it. I suspect even the data center people prefer "opt in" versus "opt out" here.

My impression is that the losses are more likely than the wins here. > > > When the user says impacting performance > > is ok then doing that is fine of course, but not by default. > > that's a fine kernel policy. > > Distros will override this policy if their users tell them they're > willing to do the tradeoff.. they will pick that default.

I'm not fully convinced that was done intentionally in this case. If there's an explicit setting somewhere that's fine anyways, but I think here it more looks like a mistake.
