Some kind of routing is already implemented on hosts.
honto???
your mobile phone is multihomed, as is this laptop I'm typing on.

routing != multihomed

it's not an autonomous system it's embedded inside one or more of them...

it most definitely makes a forwarding decision which in this case also
requires address selection.

try rfc 1812

   A router connects to two or more logical interfaces, represented by
   IP subnets or unnumbered point to point lines (discussed in section
   [2.2.7]).  Thus, it has at least one physical interface.  Forwarding
   an IP datagram generally requires the router to choose the address
   and relevant interface of the next-hop router or (for the final hop)
   the destination host.  This choice, called relaying or forwarding
   depends upon a route database within the router.  The route database
   is also called a routing table or forwarding table.  The term
   "router" derives from the process of building this route database;
   routing protocols and configuration interact in a process called
   routing.
