This is a win, not an issue.

If a host is using multiple interfaces to a subnet, such as a link aggregate, 
then this abstracts that L1 phenomena from L3.  While Ethernet aggregates are 
already common today in the Enterprise, they are about to become much more 
common in the service provider space, and the fact that L3 meddles about with 
them causes no end of grief.

The downside to this is that you can't really use L3 tools to manage your 
aggregates, as the components are no longer addressable (pun intended ;-).
