Suppose we run with Snowflake IDs for a while and then change to another ID generator. Assume `generateId()` outputs do not clash. Still, do we expect `systemIdForNode(X)` to return the same value for all generator implementations and for all possible values of `X`? -- This is an automated message from the Apache Git Service.
