I believe there was some technical thing that seed nodes do that others don't so some forum thread I read some time ago that suggested to not make all cassandra nodes seed nodes for some reasons.
But I can't find the reference so far and I also always have all nodes in seed node list xref — Tigraine. Sign up or log in Sign up using Google. Sign up using Facebook.

The seed node designation has no purpose other than bootstrapping the gossip process for new nodes joining the cluster.
Seed nodes are not a single point of failure, nor do they have any other special purpose in cluster operations beyond the bootstrapping of nodes. This single datacenter example has 5 nodes, where nodeA, nodeB, and nodeC are seed nodes. DSE 6. Release notes Release notes for DataStax Enterprise. Installing DataStax Enterprise 6. Configuration Information about configuring DataStax Enterprise, such as recommended production setting, configuration files, snitch configuration, start-up parameters, heap dump settings, using virtual nodes, and more.
Initializing a cluster Initializing a DataStax Enterprise DSE cluster includes configuring, and choosing how the data is divided across the nodes in the cluster.
Initializing datacenters Determine whether to use a single or multiple datacenter deployment per workload type.
Setting seed nodes for a single datacenter Overview of setting seed nodes for a new datacenter. Use cases for listen address Various use cases and correct cassandra. Initializing single-token architecture datacenters Deploy a single-token datacenter when not using virtual nodes vnodes. Security DataStax Enterprise 6. Operations DataStax Enterprise operation topics, such as node and datacenter operations, changing replication strategies, configuring compaction and compression, caching, and tuning Bloom filters.
Risks:old partitioned replicas, different clusters, even malicious nodes, so on. So a cluster can be defined by some starting nodes contain at clear addresses and it can be reference for that cluster for any new nodes to join in trust-table way. After some time the seed nodes can go away, then the cluster will keep on.
