Unlikely in production datacentre/cloud environments, indeed, although some of the mid-range kit like LX2160 does start to blur the line of what might be considered "server", and that's one example which *does* have full-featured DT support (even if it also aspires to ACPI...)
What I thought was worth clarifying for the general audience is that the relevant aspects of "server" here should in fact still be possible to reproduce on something like a Raspberry Pi or a tiny QEMU VM, if one can figure out the ACPI runes :)
Thanks, Robin.
