That is a very questionable proposition. Today, the transport layer
measures round trip times to manage retransmissions, and maintain window
sizes to match sending rates with available network capacity. In a
multi-homed environment, you would expect the transport to assess RTT
and capacity for the various available paths and to make intelligent
decisions about which packet goes on what path. Clearly, you want some
aggregation, but there is certainly value in providing the transport
with handles for directing traffic one way or another, which implies
dealing with addresses or locators.
