Yes, it is important. At least for us, changing this value to 0 was
enough to have a working cluster.
As I understand it, the value 1 is a protection against DOS but, in
the case of Keycloak prevents each node to discover the others. In a
controlled environment (as recommended in the keycloak docs), I see no
problem enabling it.

I'm far for expert, so maybe someone will have a better idea.
