The example given was "spam", which strikes me as a label attached to a message somehow (perhaps as metadata) and not a phase of message handling enroute to its destination.

I think "other" implies the message is entering some kind of queue state that will introduce an atypical delay, where "none" is an explicit statement that this is not the case.  They are semantically different.
