Does XCP-ng support Linux KSM? If not, could it in the future?

One of the BEST features of linux KVM is the KSM feature, which deduplicates the memory of various running VMs.
But, it's my understanding that this is a Linux Kernel feature, not a KVM specific feature. So, is this feature available/supported on XCP-ng? If not, could it be in the future?
Thanks for any info!

Xen isn't Linux. When you boot on XCP-ng, you boot on Xen first, then the "control domain" will boot first (aka Dom0, aka what you think is the host but it's not).
This has to be implemented inside Xen, and I'm not sure that's the case. Let me ask around.
