Review Comment:
Actually, to simplify this merging logic, I'll use empty list in Pair<List,
List> even if there is no optional segments, but when to creating the
InstanceRequest, I'll set optionalSegment to null if it's empty, as I found
there are places in multi-staged query that don't set this field when creating
InstanceRequest, so don't set this field (i.e. leave it as null) to be more
backward compatible
