qemu-block-rbd be removed ?

[vrms <vrms@xxxxxxxxxxxxx>]

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?
