I tend to say that
disabled means: Take requests if their routing information matches mine but
no other ones.
stopped means: Take no requests at all.
enabled means: Take all requests.
Wouldn't 'standby' be a better name for the functionality you described as 'disabled'? IMO 'disabled' means 'never use, not startable', and 'stopped' means 'don't use in this state, startable via admin interface'.
