> In Blueprint deployments it is supported to specify a host predicate and host count to
control which hosts and how many hosts will automatically join the host group. In case later
is decided that less hosts to be used for the host group thus only a few hosts (less than
the original host count) will be provisioned currently there is no way to remove pending host
requests (created for hosts never joined to the cluster) so actually reducing host count for
a host group.
