I think the main benefit of using microseconds would not be sortability between servers, but sortability between backends. With the current counter approach between backends we only have sortability at the millisecond level. However, I don't really think it is incredibly important to get the "perfect" approach to filling in rand_a/rand_b right now. As long as we don't document what we do, we can choose to change the method without breaking backwards compatibility. Because either approach results in valid UUIDv7s.
