Return Type of MultiChannelNameResolver

Hi,

Why are there different return types for these interfaces?

Code:

---

public interface MultiChannelResolver {
    List<MessageChannel> resolve(Message<?> message);
}

public interface MultiChannelNameResolver {
    String[] resolve(Message<?> message);
}

---

Could the MultiChannelNameResolver also return a List?

Code:

---

public interface MultiChannelNameResolver {
    List<String> resolve(Message<?> message);
}

---

Regards,
Thomas
