The answer
It is well known that the priests are taken in procession (after they depart), around the altar which they have served, and to which they have dedicated their lives. But as far as a deacon is concerned, if he is a wholly consecrated deacon who has dedicated himself to the ministry, who has no other job apart from being a full deacon and who has been blessed by the bishop laying his hand upon him and who is entitled to wear clerical dress, then it is quite all right for his body to be taken in procession around the church, in view of the fact that he has devoted himself to its ministry.
But the lower ranks of deacon, from Chanter to Sub-deacon who have not received the hand of ordination upon them are not entitled to this procession, because they have not devoted themselves entirely to serving the altar.
