FYI, I just merged patches that implement this in libvirt:
133d05a15e qemu: capabilities: fill in domcaps <memoryBacking>
e27e22585a conf: domcaps: Report <memoryBacking>
# virsh domcapabilities | xmllint --xpath
/domainCapabilities/memoryBacking -
<memoryBacking supported="yes">
<enum name="sourceType">
<value>file</value>
<value>anonymous</value>
<value>memfd</value>
</enum>
</memoryBacking>
