Large Clusters use external include file

I have a suggested patch as I have a cluster of 3000 servers and putting 3000 IP addresses in the csf.conf file seems to be a really ugly solution.
My suggestion is to include the possibility of an include file as follows:
1.) If you have only a few servers in your cluster, configure the CLUSTER_SENDTO and CLUSTER_RECVFROM as normal.
2.) If you have many, start the config of CLUSTER_SENDTO and/or CLUSTER_RECVFROM with the word "Include" followed by a space and then the path to the include file with the IP's (one per line) e.g
CLUSTER_SENDTO = "Include /etc/csf/csf.cluster_tx"
CLUSTER_RECVFROM = "Include /etc/csf/csf.cluster_rx"

I have patched the csf executable (/usr/sbin/csf and /usr/sbin/lfd ) with the following:
