Makes sense, not sure why we were assuming all CRDs have the same name. I followed the code path and based on https://github.com/rook/rook/blob/master/pkg/operator/ceph/object/controller.go#L507 this should not break the non-multisite deployments.

I completely missed that the PR was against release-1.7 branch, my bad but next time please send a PR to the master branch first, and then we will backport it... Thanks!
