> In CASSANDRA-10134 we made collision checks necessary on every startup. A side-effect
was introduced that then requires a nodes seeds to be contacted on every startup. Prior to
this change an existing node could start up regardless whether it could contact a seed node
or not (because checkForEndpointCollision() was only called for bootstrapping nodes). 
> Now if a nodes seeds are removed/deleted/fail it will no longer be able to start up until
live seeds are configured (or itself is made a seed), even though it already knows about the
rest of the ring. This is inconvenient for operators and has the potential to cause some nasty
surprises and increase downtime.
> One solution would be to use all a nodes existing peers as seeds in the shadow round.
Not a Gossip guru though so not sure of implications.
