Sure, but there may be latencies or so between nodes which may bring
problems, and it is always hard to troubleshoot this kind of problems.
Sticky session generally lowers probability of this kind of operational
problems, this is why I like them and use them ;-) But correctly
configured replication is necessary even in case of sticky sessions to
have failover.

Some loadbalancers are able to make sticky session on his owns, even if
application itself do not provide any cookie. We use this on RHD
website, we have F5 loadbalancer which handles sticky sessions for us (I
think it creates his own cookie), and is able correctly failover when
keycloak node dies.
So don't tell your users that Keycloak doesn't support sticky sessions
at all, it works with sticky sessions correctly if provided by
loadbalancer by some way not relying on cookie provided by Keycloak
itself. ;-)
