When using a replicated stream a consumer with a starting sequence could be created on a follower that's ever so slightly behind on applies. If the starting sequence is higher than the stream's last sequence we would clamp it down.
We should not be clamping it down, and must respect what the user/client gave us. That ensures any messages the user/client gets are always
message.seq>=starting_seq
as well.However, if the consumer is used for mirroring/sourcing then we should still clamp down.
