Hmmm. Good question. Section 4.4 of the spec[1] states:

"The initial sender sets the ultimate destination in the reverse path..."

It doesn't say that the sender _cannot_ insert additional <via> elements
into the reverse path after the one representing the ultimate destination. It
does seem that intermediaries are limited to the addition of a single <via>
element to the reverse path if you read section 4.4.3 strictly:

"If a "rev" element is present then add a "via" element as the first "via"
element listed in the "rev" element with a value indicating the reverse path
endpoint."

My intuition is that the intention was to limit any node, including the
sender, to the addition of a single <via> element to the reverse path, but
that is pure speculation. Maybe one of the Authors will respond.
