Yes, this would be used for replication of ILM expiry rules removal to other sites. In this case when we remove the rules, we set current time at expiryUpdatedAt and using that this removal is replicated to other sites as other sites would have older/no value of expiryUpdatedAt

So this is a ILM configuration?

So this option is like enabling ILM site replication vs not?

Kind of. For enabling replication of ILM rule removal across sites in case of site replication enabled. If not this flag doesnt have any impact. Also this flag is not saved as part of ILM config, rather considered for setting expiryUpdatedAt field of ILM config. Because in case of ILM rules removal as well we want to update the expiryUpdatedAt field for the ILM config so that while replication of expiry rules, we know that there was a removal with latest time and other sites as well should remove the rules.
