qemu-block-rbd be removed ?

I am running qemu/kvm on a Manjaro Laptop. There is a thing with a package named ceph-libs being removed from manjaro repos apparently. This requires to build it from AUR which fails. The only reason for ceph-libs seems that apparently qemu-block-rbd depends on it. However nothing else seems to depend on qemu-block-rbd. Can anybody tell me whether in your eyes qemu-block-rbd may be save to remove and likewise resolve this problem?
