Yes, it is excluded. If you look closely, if seed list is set to be the local
node, "seeds" list in Gossiper will be empty as well. We are preserving this
logic.
What did not work was that if you set the seed to be some other node from the
local one, then if you set that seed to that node itself again, it will not
change it - the underlying list will still contain the remote node. We fixed
this very issue.

> During re-deploying lots of Cassandra nodes I've observed that some nodes
> does not reliably reload the seeds when {{nodetool reloadseeds}} command was
> issued.
> After the seeds list was changed in the config:
> {code}
> $ grep seeds /etc/cassandra/cassandra.yaml
> - seeds: 10.90.44.82
> $ nodetool getseeds
> Current list of seed node IPs, excluding the current node's IP:
> /10.90.40.86:7000 /10.90.44.86:7000
> $ nodetool reloadseeds
> Updated seed node IP list, excluding the current node's IP: /10.90.40.86:7000
> /10.90.44.86:7000
> {code}
> At this instance the following line was logged to debug.log:
> {code}
> DEBUG [RMI TCP Connection(103568)-127.0.0.1] 2024-11-04 14:04:27,638
> YamlConfigurationLoader.java:124 - Loading settings from
> file:/etc/cassandra/cassandra.yaml
> {code}
> However, getting the old list:
> {code}
> $ nodetool getseeds
> Current list of seed node IPs, excluding the current node's IP:
> /10.90.40.86:7000 /10.90.44.86:7000
> {code}
> These nodes read the seed list only after Cassandra was restarted:
> {code}
> $ sudo systemctl restart cassandra.service
> $ nodetool getseeds
> Seed node list does not contain any remote node IPs
> {code}
> Note: this was observed on a seed node.
> Observed on Cassandra 4.1.7.
