Comment 4 for bug 1627083

For strongswan, I found a reference in a 2018 workshop to work on xt_cluster support: https://wiki.strongswan.org/projects/strongswan/wiki/Linux_IPsec_Workshop_2018

No open bug reports about moving from ipt_CLUSTERIP to xt_cluster, just references in old bugs about how that was wanted, but just not done yet.

For pacemaker, I couldn't find results even mentioning the problem, other than this bug.

Looks like it will be some time still until ipt_CLUSTERIP is abandoned.
