Doesn't appear to be to me:

This is why I queried the impact. Does anything in libvirt/qemu need
to be rebuild for a new soname, or patched to deal with the
aforementioned binary name change?

As a side note I'm not sure why quemu needs a hard dependency on ceph,
its very usable without it and could remain an option.
