Those aren't queueing states though; they're metadata about the
message.
I think I don't understand what this means.
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.
Use of the clause requires a new Received header field. The condition
the 'none' value seems intended for is for typical header fields as are
generated today. Either these should get meaningful labels or the
existing label 'other'
should suffice.
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.
