I left one idea.
Also, if you find that the PR build fails in the BWC tests because an ML usage object is getting serialized on the wire between 6.5 and 7.0 before your backport, the solution is to change the BWC constants from 6.5.0 to 7.0.0 in this PR, then change back to 6.5.0 when you backport to 6.x, and finally push another commit to master setting master to 6.5.0 again.

Rather than use 0 in the case of "unknown" in a mixed version cluster it would be nicer to have a specific "unknown" value, say -1, and then not include the count in the JSON output if it's unknown.
For example:
if (in.getVersion().onOrAfter(Version.V_6_5_0)) {
this.nodeCount = in.readInt();
} else {
this.nodeCount = -1;
}

Going with the approach of not printing "unknown", this can be:
if (nodeCount >= 0) {
builder.field(NODE_COUNT, nodeCount);
}
