------------------------------------------------------------------------
{quote}I remember there is sthg in Gossip to check the version of the whole
cluster.{quote}
There are some methods in {{Gossiper}} for this, like {{getMinVersion}},
{{hasMajorVersion3Nodes}}, etc.
I guess we would need to extend those to propagate the compatibility mode, or
perhaps directly declare the node to be on that version, not sure. So a
coordinator rejects large deletion times if there are nodes that aren't on 5.0,
or that are in 5.0 configured to be compatible with an older version.
I don't think we need a feature flag for the extended deletion times if we have
that compatibility mode. I mean, the range of representation of deletion times
doesn't seem something to be turning on and off at will. I think we only need
to avoid it during upgrades.
