It sure isn't mentioned in the documentation.
If it was, I would never have used it, and I imagine I'm not alone.
QEMU might be an emulator project where people expect quirks, but KVM
and Xen are professional virtualisation platforms competing with
VMware.
It is really not very professional that the documentation places "your
data is not safe" formats on an equal footing with safe formats -
without saying anything about it - and doesn't even recommend one or
the other.
That said, maybe Microsoft is doing the same thing - their
documentation happily recommends their VHD format if you're not
concerned about running out of disk space, and it's maybe VHD has
similar corruption windows.
