When things come to VMs or containers, developers and users tend to be sloppy regarding the hardware being used, and they are not usually aware that the database running within it is sensitive to such details. Many folks use Postgres, so IMO having defaults which are safe without relying on hardware characteristics is a rather sensible approach. (Got bitten by that in the past, not everybody is careful).
